incorrect choke adjust ment. when cold if choke is working correctly the car will idle higher until warm enough for the choke to release.It Depends on the year of the car as to whether it has a choke or not.

The temp sending unit or gauge is bad, probably the sending unit.
My Talon will not break 3000 rpm no matter what gear it hit's 3000 then drops back down to 1000 and ideas on why?
Almost all semi-modern and modern vehicles have a rev-limiter which operates in park and prevents the engine from overrevving and causing damage in the event that someone floors the gas pedal in park. I am not an expert on the Talons or Eclipses, but I think it would be worth checking out the rev...
Why would the Check engine light only come on and stay when engine starts up warm. Engine light will not appear if started and ran from cold 1998 5.7 liter Vortex?
If the battery is tired and the engine is hard to start hot that could set a low voltage code.But the only way to know is to have the computer scanned
Why does my 1986 Camry sputter and backfires when first cranked It does this at cold startup and wants to shut off when giving it gas. Once it is warmed up and driven it seems to run ok.?
Your car is running to rich meaning it's getting to much gas.

You have a 1989 jetta gl runs very well while cold and after it warms up gets very noisy and the oil pressure light comes on Once you get the engine over 3500 rpm it goes back off. help?
You probably have excessive clearance in the rod bearings that causes rod knocking when the oil thins from the heat. While the oil is thick it provides a little cushion between the rods and the crankshaft but after it warms up the oil is a little too thin to help out. You can try using thicker oi...
Why does the ac work when parked but when you drive your car it blows hot then cold and idle goes up and down?
Many ac systems use engine vacuum to operate the ac controls. You may have a cracked or disconnected vacuum line that feeds the HVAC system. Check the vacuum lines under the hood, that is where they would most likely be damaged. A vacuum leak would also be the cause of the erratic idle.
First you must check the ISC motor ( idle speed control) operation. Its located by the throttle body. It controls idle and high idle speeds. Good luck
1991 olds siloette transmission disengages when car warms up to normal operating temp and will not engage again until it sits idle for about half an hour?
Have you checked the tranmission fluid lately? Have you had the filter and fluid changed lately?
I had same issue, I had to replace a computer module and the buttons on the dash for it to be fixed. I am sure only one was the issue, but you know how Mercedes is once they install it and it doesn't fix it they don't want to take it back out. They also tried to replace the air shock seals, but t...
If the rpm on a '96 Kia Sephia is jumping up and down and sometimes the car is shutting off can you fix it yourself?
You can change the fuel filter and that might do it. If it doesn't it can get quite complicated. Take it to a good mechanic. Also, try replacing or cleaning the spark plugs, distributor cap, and wires attached to the spark plugs. I had the same problem with my Sephia. A little tune-up should fix ...
Can driving on a cold morning without allowing the engine to idle and warm up cause the engine to crack or be damaged?
not typically , extreme lower temps won't allow the engine to move quickly = it is better to warm the engine some 2-3 minutes minimum. the cracks could be from frozen water (not enough antifreeze) in the coolant passages .
There is somthing wrong with the idle the idle fluctuates all the time and if the car is not warm enugh the idle will go all the way down and the car turns off for a 1989 Honda accord?

What happens when the clutch pedal goes down by itself when gently touched and will not come back up?
I suspect you have a hydraulic clutch assembly. what probably has happened is one of two things (1)-a fluid leak, check fluid level at clutch fluid reservoir and for a wet spot on the ground from the leak, (2) the master or the slave has failed--the master aka the master cylinder at the clutch pe...

I have the same problem with my 99 SL2. No clue what is wrong.
What does it mean when your car's engine races revs up and down while it is warming up in the morning?
When an engine is warming up the car may idle erratically. This happens because the air may be to cold and the colder air will cause abnormal combustions to ensure in the engine. The computer is set to make the engine function under certain conditions, such as having the engine operate at an opti...
If I replaced the fuelfilter pcvvalve plugs wires ignitioncoil and serviced injectors why would my 1988 bronco ii start and run great when cold then die when warmed up and turn over but not start?

1992 c2500 6.5 diesel trans will not go into overdrive when it warms up but when first crank and drive it wil work until it warms Anyone know why?
Try checking the trans fluid. The level of the fluid drops when the engine becomes hot. Check the fluid with the engine idling with the trans in park.
How do you increase the RPM from 650 to 750 when in park for a 1997 Saturn SL1 with automatic transmission as it doesn't idle smooth at 650 rpm?
You can't adjust the idle, it is done electronically. You may have something needed as simple as a tune up or a vacuum leak or it may be more serious such as a burned valve.
Why would white smoke come out from under the hood when it is cold outside and the car isn't overheating?
It may not be overheating, but you could still have a coolant leak into the combustion chamber, from either a head gasket or intake manifold gasket.
What would cause a thumping sound from the front of your car and a grinding sound when decreasing speed and excabberate the knocking when you turn slighly to the right Worse after car has warmed up.?
Those details have the classic sound of a worn constant velocity (CV) joint on the right side passenger wheel. If it is found to be bad, remember that these days it may be cost-effective to replace the whole axle on that side.
Why would a 1998 Honda Civic idle speed drop to almost zero when you start it up It idles a 1000 to 1200 for a few seconds and then drops to around 300 or so?

Your 2002 Mazda 626 4cyl keeps over heating when driving down the street not even 1 mile But when left to idle in park it will not over heat what could this be?
I'd start by checking the coolant and look for leaks. I'd go further by seeing if the thermostat was good. You can grab hold of the upper hose on many cars and feel if water is flowing or getting hot.Is the fan working when your parked? Is there anything in front of your radiator. Is the water pu...

How can you repair a car door lock when the inside button will not budge up or down and the key hole has turned sideways?
Hey Donna==You need to pull the trim off of the door and see what has gone wrong with the linkage. Sometimes the trim is very hard to pull off and there are hidden screws.You might see if a manual at Auto Zone has the removal of door trim in it. GoodluckJoe
What might be wrong if your car shakes when you start it and when you drive it the car bounces up and down and the hood comes loose. How do you fix this?

What is the cause of the squeaking in my 2003 beetle It squeaks when the wheels go around but not when I brake and also when I get out and when the door shuts?
Could be that your disc brake pads need to be replaced. There is a metal clip that will begin to rub on the rotor when the pad wears down to a certain point. Applying the brakes puts the pads ahead of that clip, ergo the sound goes away while stopping.The door squeak is solved by some general pur...

When you accelerate on your Chevy Z24 the car does not pick up any speed until it hits 3500 rpm then it feels like it jumps into gear what could be the problem and how can you fix it?
First, I would have your transmission checked. It sounds like the transmission is starting to go. I would rule this out first. Also, you could check the level of your transmission fluid, If it gets too low, it will make it start to slip, if it is low, check for a leak! Hope this is helpful!
What causes a car to run rough after it sits then run smooth after you let it run awhile It does this in the morning and sounds like rubbing sound when you make a right turn?
The only way to find out is to take it to a mechanic who has an engine analyzer. The rubbing could be caused by a loose mudshield (or a dozen other things). For rubbing sounds, you might want to check the clearance inside the wheel wells when fully turned to the right. (Possible tire contact with...

Why is it that a 1989 Honda Accord Starts up but when the key is let go it shuts off As long as the key is held in Run the car does not shut off What can cause this?
Check the ignition switch and the coil resistor if the Honda has one. When the starter is engaged there is a direct connection to the coil. The intention is to give the coil a little more voltage when the starter is engaged. If the ignition switch isn't connecting properly you won't run when you ...

What cause my car give out big white smoke from exhaust with a rustling sound every time after left turn when I step on the gas. It runs smooth and accelerates well when I drive straight.?
White smoke from the exhaust is a sign of an internal coolant leak. Coolant is entering the combustion chamber. One cause is a blown head gasket. Stop driving this car immediately, and have this looked into or you could possibly ruin the engine.
91 Beretta starts but runs rough and is backfiring and blowing black smoke when able to get it to stay going running not so rough the car would stall and if i held the gas on was overheated by home?
sounds like coolant temp sensor is bad but also sounds like cat might be pluged
What is causing your 1993 probe 2lt to burn oil sometimes from a cold start but only about 10 seconds after the engine has been running ie the smoke is not immediate and it only does it sometimes?
Worst case scenario: you have bad piston rings. In the first 10 seconds, your car is pushing oil into the cylinders. Then it burns (white smoke). When the car warms up, the rings seal better and the smoke dissapears. Borrow a compression tester from Autozone (free), pull the spark plugs, and chec...

there's probably some kind of electronic sensor that's now on the fritz. You need to have a diagnostic check done on it. Take it to an auto parts store first. Most of them have the tool that can do that. If you take it to a repair shop they will usually charge you alot to have it checked. It's us...
What causes my brand new mazda3's engine to almost stall after starting up the car but then regains the rpm and sometimes when i start the engine shakes more than usual. It all happens randomly?

Would an 88 Chevy Celebrity run fine for around town use with no damage to the car if you unplug the torque converter so it will not lunge violently and die on hot days?
If the "lock-up" clutch on the torque converter is getting engaged at inconvenient time you would get the conditions that you describe. The lock-up torque converter is there to provide direct-drive when you are running at highway speeds. That can give you a little better economy. If you un-plug t...
While driving my car the accelerator would not work when you push the gas. I turned the car off and it did not start back up again. whats the problem?

Hi can any body help i have a 1998 Ford Fiesta 1.8 diesel van used jump leads to start a mitsi shogun started shogun fine when removing leads from fiesta the engine stopped and now will not start?
Did you maybe spoil a connection on your battery e.g. one of the small wires that feed your ignition. == A lot of newer cars can have their ECU fried when giving a jump start. But, hopefully the battery has cooked as this will only cost you around £40 to fix rather than £££'s for the ECU.
