Hi, what these readings are saying is while your car is idleing it is giveing the eng more fuel then it needs. You did not say anything about tune up but this is always your first step with a driveability prob. If this has been done properly look for a vacum leak on the engine. Go to a auto parts store have them scan, {usually no charge. This should give you an idea of what is going wrong. Let me know when you have these things done thanks billymac
