need help??
its a 02 z28 here are the facts
car stumbles at low rpm,
it idles a tad bit over 500
at a stop it will stumble in the 300-500 range,
i cant start the car untill the fuel pump is FULLY primed,
i just cleaned the maf with maf cleaner and it helped it lil but not for long,
i changed the wires and spark plugs cause i though it would help but didnt ,
it will usually get worse after i drive it for a bit but sometimes it starts doing it right away
if im at a stop though and press the gas a tad bit n hold it at a 700 rpm range it will be fine so i think the throttle body needs to be adjusted but i think thats not the problem considering i only tried doing that once cause it was stumbling bad
please help the stumbling is driving me insane

mines doing something like that, but minus the fuel pump thing...mine starts right away...but when it warms it has really bad timing, no spark and dumping fuel...very bad idle..changed the maf ran fine for a while but now its back to its old tricks...
i believe it might be a bad censor wire somewhere...you dont have any codes do you?
