Response . My son has a 1989 Pontiac Bonneville le with a 3.8 Liter engine with Air Conditioning. He was experiencing a stagnation during the driving, and intermittent problems restarting the vehicle unless he waited for a while. He also had problems to restart the car after about 10 minutes. If it ran, the car runs fine (that is to say, no hestiation or shaking). This does not seem to display any of the attitude, acceleration or turning issues that would need to bring forward. The "Service Engine Soon' light comes on intermittently, but not worthy of mention engine noises or performance while driving. Our mechanic was able to get the Code read, which was "34 - Mass air Flow Sensor". Changed it and no longer have problems. Keep in mind that we have had the charging system check for a couple of days before I finally brought the car to our shop, but it was okay. I hope this helps!
