Bad idle help? (vid inside)
#19
I was hopin for a check engine light if it was the o2, but im assuming it wont if its not totally crapped out.
#20
im ruling plugs and spark plugs out cause ive changed that area too many times also tried differnt coil packs.
i tried .032, .028, .024, .020 didnt change a thing
.020 it got real bad.
* i run NGK7's

car stopped at a red light, light turns green, u start to go let the clucth out and give it some gas, if the clucth is totally out before 2k BLAAA it pegs the a/fs to 10:1 and it barley moves until u get past 2k and vroom back to life.
ive been reving high while letting the clucth out to get it past 2k by the time my clucth is totally out to avoid it falling on its face

update
Today i took the timing cover off, inspected timing belt and cam gears just to see if it was missing teeth, or if my cam gear(s) jumped a tooth, but everthing looks ok.
I added 2 degrees of timing to idle and it got real lean and stumpled real bad on cold start..but when it warmed up it was back to the same lope.
the only thing i got left to check, that i can think of is: o2, maf, egr, ICV and maybe tune?

You sure the feedback is supposed to read 100? the only o2 feedback i see, is read in % and the numbers flux from -.6 to 5% which seems right to me, compared to my wideband. Thats about how bad it moving back and forth.

check your cam timing i'll bet the intake cam is off a tooth seen this last month on an 03 same deal loopy idle intermittintly also to check for leaky inj. use brake clean and spray at the tops and bottoms of the inj. if the idle changes then its leaking it will speed up and smooth out.

Also the brake clean thing was one of the first things i did...i actually sprayed EVERYTHING
And did u mean leaky injector like the rubber gromet is leaking? cause i meant a leaky injector, like its dripping fuel (bad injector)

I had this problem a few months back. My o2 sensor harness under the spark plug cover had come slightly unconnected somehow. I didn't click it in hard enough when I removed it a few weeks earlier. The vibration bumped it out. It seems so simple but it had me scratching my head for a few days. I had the very same problem though it would idle just like that, sometimes die and sometimes jump up quick.

o2 connector looks good. ^^
My car has been idling fine all day, then i realized my ac has been on. I turned off my ac and back to loping.
AC on car idles @ 1000-1050 rpms -10 vacuum////smooth idle
AC off car idles @ 1050-1100 rpms -16 vacuum/// rough lopy idle
this is drivin me nuts
