1997 Pontiac Sunfire

Maybe check out the idel air control sensor. Or the throttle postion sensor. Maybe put it on the scanner ( the auto zones and advance autos have them where you can do it for free) that should bring up a code on what the problem is. I wore out my break pads because of it. The idel air control sensor is adjustable but the throttle postion sensor is not. It cost me just about 90.00 for a new idel air sensor and that fixed it. But I would put it on the scanner before spending money and having a different problem.
