Mac Posted August 6, 2004 Share Posted August 6, 2004 This most likely is a vacuum hose problem. Check all the vac hose connections, specifically the one's connected in the vicinity of the cannister inside the engine compartment on the passenger side.

canajun2eh Posted August 6, 2004 Share Posted August 6, 2004 There's a vacuum connector near the accelerator pedal that sometimes comes undone. Link to comment Share on other sites More sharing options...
