Thread: Another Won't idle thread

so iv looked around and i guess im just being blind, the car starts idles but idles very rough for about 5seconds and then dies. when it starts the car jumps to about 1200rpm and then drops to 500 then back and fourth to about 1k rpm. car will drive just wont idle, it happin out of nowhere stopped at a light it died and now idles like $hit

MAF maybe?

i unpluged the MAF and it idles. i swaped the MAF with a known good MAF and it wont idle again....

with either MAF it will drive and go above 3k with no problem

have you tried regrounding the MAF?

Yup, I don't think its a MAF problem... if I hold the pedal at 1500rpms it will stay on but is sounds like ****, like its breaking up(mind you its na)

i assume no codes are being thrown? how do the plugs look? does it seem to leaning out or running rich?

when you say "if I hold the pedal at 1500rpms it will stay on but is sounds like shiit"


what does shiit mean?


like it stumbles? the rpms break up? stutters?


can we list what affects idle?

IACV valve, MAF, too much air, too much fuel, ?
vacuum leaks? unmetered air? fuel pressure regulator vacuum hose split will cause too much fuel.


any codes?

Yes like its stumbling, when I checked the. Plugs they were a little white



Not sure the engine light is normally on because of my flywheel, and as $hitty as its running I don't want to drive it anywhere to hook up a scanner and possibly screw anything up

white plugs means your running lean iirc, black soot means rich.



try checking fuel pressure

Ill check that when I get home, I'm actually planning on replacing the fuel filter as well. And get some fresh plugs in there
