V10 Stalls
 

I have a 2001 Triton V10, with a Banks added on about two years ago.

Engine began hesitating and intermitten stalling out about six months ago. After each stall, I was able to restart before it came to a complete stop. Does not happen at all times.

Ford thought that it was fixed in January but when I took it on another trip in may, it was still the same as before. Now they are unable to find the problem.

Has anyone had a similar problem?

Thanks,
David

Haven't heard about anything like that.

How many miles are on it?

Do you have a tuner? Does the Banks come with a chip that plugs into the computer? If so, remove it, make sure the contacts are clean, etc, and if it's still doing it, get Banks to replace the chip.

I had a Superchips in my '96 T-bird 4.6L and it went bad - the car would stall mid-gallop, re-start on it's own, etc, and NEVER log a code - because the computer was resetting (rebooting).

Other than that, I can think of a few other things to check out: MAF (clean it), vacuum leaks (must be a biggun), or even the PCM (computer).

Get back to us with the above answers...

Sounds like the "classic iac" problem.Idle air control solonoid behind the throttle body plenum.

I didn't mention the IAC because it sounds like it's doing it in gear while moving... but I guess it could be ...

Has 26k miles.

Don't know about the chip or tuner but will find out from Banks.

THinking more on this, is it when you let off the gas that it stalls? Or does it cut out while keeping speed (as in, foot on the gas)?

My '99 V10 would stall out while moving (though I was usually just idling along in traffic, not at normal driving speed). IAC fixed it.
