adamzan Posted September 20, 2009 Share Posted September 20, 2009 (edited) Are you absolutely sure they put the timing belt on right? The shop put my dads on off by one tooth, after you set the spark timing it ran ok but still "not right". Like you're talking about.

adamzan Posted September 21, 2009 Share Posted September 21, 2009 If the timing is way off the belt is probably off a tooth. Also is the CEL on ? Link to comment Share on other sites More sharing options...
