91 Cutlass Won't stay running while in gear

#1

My car won’t stay running. We’ve replaced the spark plugs, the air and fuel filter, the idle air control and beat on the catalytic converter (lol I know it’s bad but it did make a difference). Honestly I got the car for free, and I don’t love it but it is a necessity. I don’t want to through a bunch of money at it if it isn’t an easy fix. Any ideas?

“Won’t stay running while its in gear” doesn’t say nearly enough. There are lots of ways that a car stalls.

Please describe exactly what happens - at idle, when you put it in gear, when cold, when hot (if that makes a difference). If you have a tachometer, knowing the rpms while at idle & out of gear would be helpful.

At idle and cold it runs ok. I don’t have a tach unfortunately. It seems like when it warms up is when the problem happens. It ran ok for a little bit and then the problem started again. I have thought that it might be a vacuum leak but I have no idea where to start looking or how to go about that process.

“Please describe exactly what happens - at idle, when you put it in gear”

In other words: “I start the car and it…[fill in the blank]. Then I put it in gear and it…[fill in the blank]…I come to a stop sign and …etc.”

Either your engine is just running like crap & can’t handle the load when you put it in gear. Or your torque converter clutch could be stuck on & stalling the engine. These are two very different things and the first thing is for you to say enough for people to guess which it is.


#5

Usually when an engine stalls when the vehicle is put into gear, there’s a problem with the fuel pressure.
