2001 Ford Mustang GT
4.6L
60K Miles
Hi, I'm not a car guy, I hope someone can help!
I have a low mileage 2001 Ford Mustang that's been running great. All of a sudden it's been having trouble turning over. It's not cold weather (we live in a mild climate), and it's not the battery (battery is new and Sears checked it out, it's fine).
Basically, when I turn over the car and push the gas pedal, it turns over fine and runs. But, the moment I lift my foot from the gas the car immediately dies.
We went under the hood and discovered some sort of a rat's nest had been built in and on the engine block. There was all sorts of straw and nuts and leaves crammed into all parts of the engine block. We have blown and wiped the engine clean of all junk.
We cannot spot any obvious problems (like chewed wiring or anything) but we believe the problem must be tied into the rat's nest somehow.
Can anyone help? I'm not a car guy, sorry, but I will try to answer any questions! Thank you!
Jay

Will the Mustang stay running if you lightly depress the accelerator? Such as about 1500 rpm's? If it does, your problem is likely in the Idla Air Control motor. They will sticl closed and not allow enough air at idle. Picture below
Being way2old is why I need help from younger minds

Thank you very much for the reply!
As you say, at 1500 RPM the car runs just like normal. When I remove my foot from the gas the car dies.
I tried to follow your advice, and removed a part that I now believe is a Throttle Posiition Sensor, not the Idle Air Control motor. I will go back now and try to explore the RIGHT part!
By the way, with the TPS removed the car behaved identically as with the part in place.

OK, I believe I found the right part. It looks much like the picture you showed, except there is a large black tube running from the face of the part to another part of the engine. I removed the part and examined it closely.
The part looks sparkly clean, with no signs of carbon buildup or gunk or rat poop or anything.
FYI with the IAC (and tubing) removed from the engine the car started for just a moment and then died completely.
So, I guess I am still looking for a solution.
thanks! Jay

Jay; I don't want to sound like an idiot, but have you checked the air filter and box? I've had cars towed in that wouldn't run because the air box was filled with dog food or bird seed. (mice). Them little buggers can get into places that you wouldn't believe. Inspect the box and the air tube going to the throttle body.

Hi, Loren, thanks for the reply! You're talking about this unit pictured, right? We just pulled it out and examined it. It seems to be clear and clean. THe large black tube it feeds into has a protective screen in front of it so nothing came into the tube through the air filter container.

Yes, that would be the fresh air tube. Find the black plastic box that the air filter is in and check it, also. The MAF sensor can be removed and cleaned, also. You can use carb spray or electrical spray. Let it dry before reinstalling.
