jdm lumina Posted October 5, 2008 Report Share Posted October 5, 2008 i have a 91 lumina euro with a 3.1 in it. i've been having problems lately. problem 1- car has a hard time trying to start problem 2- when the engines get hot the rpms start to jump and sometimes cut off. when its real hot it wont even start back up. we knew it was the cat so we just put a straight pipe inplace of the cat. but the car stills runs fine when its cold but when its hot the rpms still jump around and the car cuts off. im lost now. i need help. any suggestions on what the problem might be?

Crazy K Posted October 6, 2008 Report Share Posted October 6, 2008 ignition module... or crank sensor. Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted October 6, 2008 Report Share Posted October 6, 2008 Could be coils on their way out too. Or ICM or CKP Sensor, like Ken said. Quote Link to comment Share on other sites More sharing options...
slick Posted October 6, 2008 Report Share Posted October 6, 2008 Yep, i'd start by having the ICM/Coils tested. As for no restart when hot, possible bad starter solenoid. Seems somewhat common. Quote Link to comment Share on other sites More sharing options...
