Question about 1993 Oldsmobile Cutlass Supreme

2 Answers

I have a 1989 olds Cutlass Supreme sl 3.1L. I am having problems with it trying to stall and acting very sluggish at times. Especially when I am at a stop light or just got off the highway. Engine sounds like it is having a hard time keeping up with the idle. I have put in a new IAC valve, plugs, air filter, cleaned the injectors.

What makes the fuel pump not kick on on a 92 Oldsmobile Cutlass


There is a red wire close to the battery in the front. It's not connected to anything. Apply positive voltage and that will run your pump for testing purposes.

On cold start up in the morning the transmission will not come out of 1st gear for a very long time! 1989 cutlass supreme sl 2.8


With a transmission there is not a lot you can do at home.Most problems are the fluid level.Start the car and fully warm it up.Move the gear selector through all the gears a few times and end in neutral.H/brake on.Now, with engine still running and in neutral,check the fluid level by removing the transmission dipstick.Clean it and reinsert it and recheck.If it is low,add some fluid through the dipstick tube.Slowly or it will run back out.I hope this helps you and this is about all you can check at home.

Stalling issue


If your car has high miles and you haven't changed the coil packs, that may be your problem. Bad coil paks will cause hard starting, rough idle and stalling.
