I have had a lot of trouble with my 1990 lumina! i now understand why there are not more of them still on the road. When it starts consistently and STAYS running it is a great car! it handles like and dream and i cant complain on the pick up and go either... when running good!
i have had some issues with it since it is an older car and i must say this is a used engine that came out of another similiar to lumina but it is still a 3.1!
The car has ALWAYS had issues with stalling when backing out my driveway because it was so erratic in idling. It would idle up and down very off and on...no same variable was the same except it WOULD happen.just didnt know when or where. I had power brake it ALL the time, thank goodness it has excellent brakes!
Any ideas? just recently last week, when i got on highway i had it floored and it was like the engine was bogged down...it was almost red lined on the RPM guage and it wouldnt go no faster than 30 MPH or so
