no idle when warm?

[wed3k]

i have a stock rebuilt f22 with a Delta 272 and MRX chipped p06 with a basemap 272.

when the car is cold, it will start fine and idle at 1000.

once it warms up, it wont hold idle whatsoever. it will run fine with a vacuum leak. i had the cam timing at zero and at advanced 4 degrees

Idle needs to be adjusted? still running FITV?

[wed3k]

FITV has no coolant lines attached.

the idle adjustment screw doesnt affect it whatsoever which i find wierd.

IACV = 12.7 ohms

the white coolant temp sensor = 271 ohms when warmed up.

TPS set properly

IF you have no coolant line to the fitv you should make a block off for it imo.

why cant i just run it with no coolant lines?

You can. We have an armchair quarterback in this thread.

that term lost me.

that term lost me.

What I meant was, I don't think that guy has any first-hand experience with bypassing coolant lines on the FITV.

idk but im really open to ideas since the auto-x is on sunday and i kinda dont like vacuum leaks especially its the only way the engine can idle at the moment

forgot to add that the spark plugs are pretty dark but i think the rich issue was fixed when i advanced the cam timiing. i havent really fucked with ignition timing since i cant get the car to idle. i need to borrow an advanced timing light so i can set the advance.

sounds like a functioning FITV but non functioning IACV but
the idle screw not affecting it

idle screws ports blocked cause of being dirty, but I don't think you would have left that off in your rebuild.

i dont think it is any of those components any more. i think its getting too much fuel at idle...and/or maybe when running?

im going to put a fuel pressure guage and see what the psi is...maybe the regulator is corrupt?

i know the injectors all tested within 2-3ohms however they were off another car. i put new seals on them and there's no fuel leaks.

stock fuel pump..
