sr idle issues.

[mattx7]

heres all i know.

its an 89 s13 coupe with a redtop sr20det.

the idle doesnt surge up and down when its cranked so it didnt seem like a vaccum leak.

the maf is good, its a sohc maf, running the sohc maf plug.

aicv is clean, vaccum pressure is at 17 at idle, compressions is 150ish on each cylinder. im running open dp. new plugs, new fuel filter.

the 02 sensor is not connected and where its supposed to go in the turbo extension. theres a peice of pipe threaded in there and pinched shut.

it holds idle fine when its stopped, i can push the clutch in while in gear it will hold idle, put in in neutral when its stopped and it will hold an idle.

when im driving, it hessitates terribly when it hits boost... i let off the gas and it backfires alot...ALOT. and if i put it in neutral when driving it stalls. when i push the clutch in when driving it stalls unless i put it into gear really fast and give it gas.
