Idle Problems
 

Ok I still have Idle poblems, heres the car 2004 Mustang Gt steen racing heads, comp 270 cams, long tube headers, sct tune, 70 mm throttle body CAI, 4:10 gears etc..

The car will Idle for 30 seconds then shut off, it seems to do it more when warm. I ran the codes here is what I got

P0113 Intake air temp censor 1 circuit high input

P2197 02 sensor signal stuck lean bank-2 sensor 1

Would either of the cause the idle problem and I know how to change the O2 but not sure what need to be done to correct the P0113 Code

any help would be great

first i'd check your IAC sensor. for the P0113 code. faulty or dirty, would trip it. try taking it off, and cleaning it w/ carb cleaner, dry it off real good, and put it back on...disconnect battery before, then reconnect battery after cleaning, and check for codes.

the P2197, id check for a vacuum leak somewhere intake manifold gasket faulty, faulty pcv valve hose, faulty vacuum line hose, check your clamps on your airbox.

if not of that works, replace both sensors, reset computer by disconnecting the battery for 30 minutes, then reconnect and start.

the IAT sensor code is odd, unless its not plugged in its weird it would toss it. Who did the tuning, was it a mail order or dyno/road tuned?

I wouldn't use carb cleaner since it leaves a residue behind. Instead, get some rubbing alcohol (preferably the highest alcohol content you can get).

Humm
 

I have replaced the IAC, PCV and still the same codes, Steen Racing did the tuning.

I'm lost can not figure this idle problem out and it is annoying

The P0113 is the MAF connector. Unplug it and check for pin damage. Fix.

The P2197 is a little more vague. Could be a vacuum leak, exhaust leak, bad 02 sensor, or as simple as bad gas.
