JBuckley Posted September 23, 2004 Report Share Posted September 23, 2004 I know this is not a Caddy question but your knowledge will sure help. I have a 92 Buick Lesabre, 3800 engine, was running fine, yesterday my wife was dropping a friend of and was talking with the car idling, all of a sudden it developes a miss/ very rough idle. It was shuddering and missing when trying to accerate from a stop sign. I changed plug wires last night no help. Got up this morning went to work on car and it idled and ran fine, drove around for 10-15 minutes everthing ok, went home turned it off came out in an hour and now it is idling rough again. No codes in computer, check PVC valve ok. any other ideas group? John Link to comment Share on other sites More sharing options...
