AnswerThank you. I am not sure on how to do that. Lets deal with the missing while idle and that may fix you problem. If you have not checked the
the plugs, wires, Vacuum hoses, air filter, and connection of hoses to and from air flow meter, please do so. Check for leaks in your exhaust system. The air flow meter can cause emissions problem. Do your car have any problems accelerating? If so your air flow meter may be at fault.
Sam.
