Yours probably just needs some tune-related work to get it back into the happy 'window' of operation. Check the easiest (plugs, correct ACDELCO PCV valve, fuel/air filter, check for vacuum leaks and make sure the MAP sensor hose/port isn't gunked up).


Thanks one and all! I'm all about doing the easy stuff 1st. I'm definitely due for plugs and probably a fuel filter. Sounds like my weekend just got busy. Thanks again.

Peter
