2002 Buick Regal Q&A
2002 Buick Regal Question: trouble accelerating
These 3.8 engines are notorious for cracking the intake manifold, check it for leaks. - hemicuda
My last Buick (Park Avenue) had a similar problem.. but only when less than 1/3 full of gas. Could this be the same? If so, try keeping the tank above half and that should solve the issue... worked for me! - sfjm
Car runs great, seems to shift fine. Only problem is this accelerating problem from a stop. Service engine soon light came on, and I was told the shift solenoid code came up. Had computer cleared....
car idles fine poor acceleation rpms increase speed does not 110000 miles
Car overheat even after changing water pump and termostat LP
Engine light is on, have replaced both oxygen sensors and the throttle position sensor. This made the vehicle idle much better, but it will still cut out when accelerating.
