why is my car running like shit?

[eastcoastS14]

stock KA my idle bounces up and down under 1000rpms....lights dim in and out when this happens. It was never a big deal but for the last week the RPMs will die off and it even stalls sometimes when i put it into neutral. this happens very rarely but its a pain in the ass...the bouncing idle is pretty constant. Any ideas?

Alternator is my guess...

Search NOOB!!!

haha j/k, check your maf like stated above, also make sure to check your usual tune up items, plugs, wires ect. IF none of these are it, then i'd try taking off your IACV and spraying it down with some carb cleaner, that fixed my stumbling idle.

Alternator is my guess...

don't think it would be his alternator as long as he can start it back up after a stall

check grounds, connections, wiring for sure

take it to an electrical shop and have them test your alternator it might be going out

its not your maf you car can run fine without a maf, so i would say you have some electrical problems.

yeah I was thinking a ground somewhere, should have added this started after replacing my headgasket maybe just some bad connections....ill prob replace my plugs and wires anyway tho
