Engine Performance problem
1992 Buick Century 6 cyl Front Wheel Drive Automatic 152000 miles
My car has started running very rough. I have to floor the gas pedal for awhile to start it. It runs very rough at idle. It accellerates ok, but when I let off and coast it starts to "buck". When I come to a stop it usually dies, unless I keep my foot on the gas to throttle it up. I have changed the fuel filter, and all of the vacuum hoses. Some were split and dry rotted. Two going to the fuel canister were unplugged, plugged them back in. I put some seafoam in the oil and the gas. I started it, and it ran fine, I let it sit overnight and it was right back to running bad. The symptoms are just like a bad EGR valve? I cannot locate the valve though? Can you tell me where it is located? Or, do you think it could be something else? Thanks for your time.
have the same problem?
