Model: 98 Regency
3.8L - fuel injected
Ok. Here it goes.
Acceleration is fine when car is cold, but after warming up under moderate acceleration car stumbles and surges then under hard acceleration condition improves slightly, but more noticable when it stumbles. Another symptom is when attempting to shift out of overdrive the car jerks a few times before in gets out of OD. BUT if I accelerate quickly the transition is smooth out of OD. This just strated to happen recently and I initially thought it was ba gas, but the situation has not improved after a few tankfulls of gas. I don't want to start throwing ignition parts at the car until I have a grasp of what may be the culprit. I'm thinking a coil pack, but what perplexes me is that when cold the accelation is great, no hesitation. It's not until it warms up that the problems starts. Thanks for the help guys!
