well i finally got my jaw up and running and and getting and afr range of like 12.5 to 16/17. which i think is too lean??? maybe or am i ass backwards and thats too rich?

im not sure but i know that it is really off, could the crack in the downpipe be making it read wrong?
that a/f range tells us nothing... what are they are idle , and full throttle. and where is your vacuum on your boost gauge at idle??

iacv in warm weather does nothing after warm up. Its turning off cause your proably shorting something out dont start pulling wires out will a car is running


if you want the iacv problem go away dont run any water lines to it done. Car will warm up just fine



Yes it works 10+years of doing it and mr all motor has proably 20 years of doing it. Rock solid cold idel,900 warm

i dont have any water lines to it per your suggestion from a prior post. i put a peice of coke can in between it and the im and turned the idle screw up and it runs fine now. i just dont know how well it will start cold.

see the problem is it wont start when its cold out. i have to put my foot on the gas and hold the rpms up. this is totally impractical. it wont start at all unless i manually add throttle. but when its warm the idle is fine now w/ the coke can fix. dosent jump around at all.

well that coke can will always cause the old school warm up style.




I have never had any of these iacv problems everyone has had on any of my builds or swaps etc I have done. 10+years and I have yet to see one fail



fitv's on the other hand thats common but thats never brought up for odd reasons

yeah but i wont even idle, i could understand a real low idle when cold, but this wont idle at all, wont run without the throttle on.
