Default my idle is jumping and car is stalling out

my 06 GT has about 93k miles (just replaced my tranny this weekend with a used) and i have a C&L CAI (came with the car when i baught it used). also came SCT tuned. i've had the car about 2 years now.

over the last few weeks my car idle is jumping up and down and now it has started stalling when im coming to a stop. RMP is falling below 500 and just causing it to stall.

any ideas? only thing i can think of is maybe cleaning my C&L air filter... maybe tune up? im no mechanic so please bare with me. any info would be helpful.

thanks

Clean the throttle body.

A dirty throttle body can and does cause this to happen VERY OFTEN.

If you go to brenspeed.com they have a video somewhere on their site
if you want a tutorial on it.

Make sure to use CRC throttle body cleaner.
Other cleaners have ingredients that will EAT the protective
coating the throttle body has that you cant see on our cars.
Dont use anything else.

When was the fuel filter replaced. If it's getting clogged it will cause fuel starvation.

No problem bud!
This is a common problem that arises with our Mustangs btw.
After you clean it you might feel it's a bit more "peppy" too!

I've experience the same issue with my old Ford Explorer Sport! The fuel filter needed changed and the fuel lines needed cleaned.

If you decide to clean your throttle body, be sure to clean your Mass air flow sensor as well. Be sure to buy appropriate cleaner for both, so you don't damage anything.

everything attached correctly? no leaks in the vacuum lines?
no codes or CEL?
did it run well after the tranny swap or was it running funny from before the tranny swap?

Clean the TB and MAF sensor, change out your fuel filter, replace your CAI filter (probably should do it anyway, I bet its all nasty right now) - all good places to start
