Car Stalling Problems
Lincoln Navigator

My son has a 1989 Pontiac Bonneville LE with a 3.8 Liter engine with Air Conditioning. He was experiencing stalling while driving, and intermittent problems restarting the vehicle unless he waited for a while. He also had problems restarting the car after about 10 mins. If it ran, the car would run fine (i.e. no hestiation or jerkiness). This did not appear to exhibit any attitudinal, acceleration or turning issues that would bring it on. The 'Service Engine Soon' light would come on intermittently, but no noteable engine noises or performance while driving. Our mechanic was able to get the Code read, which was "34 - Mass Airflow Sensor". They changed it out and he no longer has the problems. Note that we had the charging system checked out a couple of days before we finally brought the car to our shop, but it was OK. I hope this helps you!
