just started happening Sunday night and it's only sometimes that it start idling like ass but once i get it above 1500rpm it's fine...it's got me a lil confused....already put a new set of plugs in and have swapped out the plues wires....gonna scan it later and see what's going on there, but the AFR is fine when it starts missing...anyone have any ideas...map sensor maybe?
A coil taking a crap? A bad rocker arm? Burned or bent a valve?
Vacuum leak, TPS, dirty throttle plates dirty IAC port.
yeah i have come pretty close to thinking its a coil pack going bad
I was thinking its a big cam...lol ,mine idles like that that too
I have the same problem, it drives perfectly fine, just at stop lights, and idling it seems to have a miss in it, and shake a little. I havent figured out what it is, but im going to try my new injectors, and a TPS
It may just be a dirty injecter not spraying, just spitting fuel.
i am getting a set of coil packs from Moze tonight and going to run a lil seaform through my gas tank to clean the injectors...see if that helps it out
im with red do a compression test first before putting parts in it
i don't think a bent valve or rocker because it only happens sometimes just out of no where...the plugs i pulled looked a lil rich but not bad...but that's my tune i want it rich at WOT..it's at like 11.8...i think something electronic cause it just comes and goes....i bent valve/pushrod or rocker would be a consistant miss
how dumb do i feel...i loaded the wrong tune into my PCM....it was making it really rich at idle and the o2's werent always picking it up fast enough to correct it....i thought i had save the changes i had made to it last week but i guess not...anyways i got it taken care of by pulling some fuel out of it
i was guessing low on headlight fluid
very low...but it's full again...at least one bottle is after last night :ugh2:Quote:

no.......mine was just from stupidity lol....but yours could be from running a slightly colder plugQuote:

if your tuner hasn't already done it you can have him bump the idle up to like 650 and that will help with it.....what size Jets you looking for?Quote:
