LITTLE PROBLEM

[clang5oh]

MY CAR SHUTS OFF ON ME AFTER IT WARMS UP. STARTS UP RIGHT AWAY EVERYTIME BUT AS SOON AS I COME TO A STOP IT JUST SHUTS OFF. WHEN ITS COLD IT IDLES JUST FINE AROUND 700RPM. ANY IDEAS. TIMING IS SET A 10BTDC RIGHT NOW. JUST REPLACED THE PICKUP COIL BECAUSE IT USED TO SHUT OFF AN NOT TURN BACK ON FOR A FEW HOURS, DAYS, MONTHS.

It actually sounds like your idle is set too low. 700 RPM cold idle is not right. And if that is the case, the IAC might not have figured out to flow more air for the hot idle. As you come to a stop, if you feather the gas, does it keep running?

Have you changed the Idle setting or could the IAC be dirty?

Good luck.

IT DOESNT DIE UNTIL I COME TO A COMPLETE STOP, ACTUALLY A FEW SECONDS AFTER. IF I FEATHER THE GAS IT STAYS ON. I HAVE NEVER CHANGED IDLE SETTING AND HAVE A HARD TIME BELIEVING THAT THE IAC IS DIRTY. I BOUGHT A FORD RACING THROTTLE BODY ABOUT 3500 MILES AGO.

The IAC could still be dirty even though you purchased a new TB. Giving it a thorough clean is never a bad thing, but I'd probably pull codes to see if anything else is causing it first.

I also think it could be the IAC Please don't type in all caps it's quite an eyesore.

is there anyway to check the IAC. or just clean it hope for the best if nothing improves pull codes. sorry bout the caps. using the computer at work and when i log stuff into our database i put in all caps and never think to turn them off.

The idle can be set so the car will idle, when hot and with no load, without the IAC. So if you disconnect the IAC and the car dies, that suggests the idle can be optimized further.

On a fox one can use an oscilloscope to measure the square wave, but I think 5N95 IAC's work differently.

Good luck.
