on a cold start, it revs to 2500

then it drops and i get a 500 rpm bob on the tach. fucking annoying, and i get an o2 cel, but i don't think that's it. as long as it stays above 1500k or so, it's fine, but less than that and it surges. i don't know what it is. i'ves swapped iacv's and maps and checked my vacuum, new im gasket, etc. any ideas?

FITV, tighten it up
IACV, clean it out with carb cleaner

Do the FITV check per helms.......

Have you swapped the TB??????

Cam change? Cam gear?

1500 rpm cold idle upon startup, higher than that and you have issues.

Try getting a race cam to idle, yours is easy, mine's a BITCH!!!!!!!!!!

haha! i dread the day i have to idle a race cam...
it's a b7/z6 swap w/ z6 tb firewall map sensor plugged in...
i swapped the iacv around, cleaned it, but still the same shit...
stock cam, stock gear...

thanks for the tips, i'll look at the fitv, that's one i haven't messed with...
