Engine Performance problem
1991 Chevy Lumina 6 cyl Two Wheel Drive Automatic 53501 miles
My car does not seem to idle correctly, when I fire the car up and let it run in park the motor seems to idle up and down. If I put the car in reverse and try to go the car will stall. Sometimes it will stall at red lights. Lacking performance when I hit the gas.
I inherited the car from my dad and he didnt drive the car much at all.
I changed the oil and filter, spark plugs, spark plug wires, and the coil packs with no better results. I have also changed the drive belt and tensioner, antifreeze and trans fluid still nothing better. No trouble codes found. I replaced the air filter, fuel filter and took it to a shop to clean the injecters and air intake. The gas tank was on empty so I dont think there was a chance for old bad gas. When I turn the key to on I can here the fuel pump run for a few seconds.
The old car stills runs the same before I threw parts at it and I dont have a clue why it runs so bad. Back when the car was new it ran great.
When I got the car the battery was new and the car was drivible.
Any suggestion would be helpful!
have the same problem?
