Well I am still having problems with my car. It doesn't want start when cold and backfires when the I press on the gas. I have to keep my foot on the pedal until it warms up. Once its warm its runs fine except it idles badly and sounds like it wants to die everytime you stop at a stop sign. I replaced the spark plugs, wires, rotor, and distributor cap today just to see if it would help and it didn't. I can't find any vacuum leaks. There are no codes on the ECU. I just replaced the AFM with a remanufactured one from O'Reilly Auto Parts. Could my catalytic converter possibly be clogged? Or maybe the car isn't taking to well to this new AFM.
