I just got a winter car, it ran great for a little.....it is a 1990 chevy lumina, Today i took it for a ride and when i came to a stop light it just stalled, lucky i coasted it in a parking lot.... i put the car in park, turned it on again and it turned on, then, i put it in drive and it stalled right away, i kept doing it and it did the same.....so i decided to go in rite aid for 10 mins, i came back and started it and it worked, i drove back home then as i slowed down again it started to studder, then it stalled right as i stopped......i waited another 10 or so mins, then took it for a ride, i noticed when going a little ways, when i would let go of the gas it would jerk....

does anyone know what the problem is?...i think it only does that when it gets hot. The car has been parked for like 5 to 6 months too...

How hot is it getting? Have you put any new gas in or any gas stabilizers since it was sitting for that long? If you have the same old gas in there that's probably what is making it run crappy. When it sits for a long time stuff tends to get gunked up ... probably just running some of that through the engine.

Aha! I think I know your problem...





It's a Chevy!

When you go to make a stop put it in neutral. IF it still dies out it might be something to do with the charging system?

i fixed the problem, when we first got it, my father and i was looking at the engine and noticed a plug unpluged, so my father pluged it, it was a pressure censor or somthing like that...and it worked fine at first, then it started getting worse, so finally he unplugged it and it worked fine after that.

cel? i had a similar experience w/ my cutlass calais most likely it's the mass air flow sensor. you can pull the codes in the same fasion as the cb7's but the connector is under the steering colum,about 1/2" x 2" w/ several pin. jump it w/ a paper clip not sure which ones to jump,i do know it's in the top row of pins,you'll hear the coolant fan come on and the cel will flash accordingly

ex> - -- is code 12 which is normal.
so on,you get the idea.

It just so happens I'm the lube tech. at a GM dealer! (Sad, but true...) Have you checked the fuel filter? You may also want to have that sensor checked out... And if I'm not mistaking, there is a recall out on that car involving the instalation of a relay to the starter to help keep excessive voltage from going through the starter... Check your local GM dealer on that one. But as cb9h23 mentioned, check the mass air flow sensor as well. It should be located somewhere in line with your intake tube. If all else fails, you could take it to your local GM dealer to have it checked out. I know most people say "I can't afford that...", but all in all, it could be money well spent. I'm not sure about where you live, but where I live labor rates are around $67 per hour, and a simple computer scan runs around $75, but won't do you any good unless you have a warning light (like a service engine light...) on. Good luck. I know it's a dumb-estic car, but at least it's not a stinking Ford!!!
