so far you guys have been very helpful and pretty accurate with the problem solving, so here i am again seeking more help!
well, my previous problem was the AFM (car would idle fine but stumble and jerk in low rpm's upon acceleration) so i purchased a new AFM about two months ago. it ran fine for a couple days then the problems came back so i bought a new fuel pump and my car has ran very good with no problems up until a week ago.
i was going about 15-20 mph and the jerkyness came back (symptoms from a bad AFM). i parked it for about 30 minutes, then it ran fine for the next 3 days. then one night it started doing that b.s. again after i warmed it up and drove off, so i let it sit overnight and it worked fine the next day.
two days ago it happened again so i opened the hood to check it out while it was idling. pulled the throttle a little and a popping noise started coming from the airbox as i gave it gas (doesnt get above 3000 rpms). the next day i tried starting it and all it would do was crank with the popping noise coming from somewhere. i was told it could be a bad catalytic converter so i cut before it and tried to start it. the engine would turn but not start, then after a minute or so, it started for a few seconds and died out and hasnt started since. i still hear that popping noise when i crank it, even with the cat converter disconnected. what the hell is going on here?
whats new on the car: afm, fuel pump, filters, cap, rotor, wires, plug, coil, and brand new bosch battery.
