Rough Idle and Check Engine Light
Yesterday I went to the store and the car was running great. When I came out of the store and started the car it had a VERY rough
idle. It drove ok from about 2000 rpms and higher and settled out after driven to a ok idle. The check engine light was now on. When I turned the car off, I again get a very rough idle. I had a half a tank of gas so I don't think I got "wet" gas as it did not do this for the first half a tank. I stopped at the gas station and filled it up the rest of the way and put some gas drier in just to see if it was possibly wet gas...no help... This morning I disconnected tha battery to reset the computer and see if that fixed it. When I reconnected the battery I would say the rough idle was worse. Infact I now have a significant drop off in RPMs when the gas is applied...
Its a 2002 1.8T 5 speed with 40000k
Any ideas/help
Tks
Peace
