Choppy idle (95 gt)

[LaserRed5.0]

Okay well my mustang will never just run or idle well idk wtf it is. Anyways at idle it sounds real lopey/choppy like its cammed, the engine will make a choking noise and you can hear the exhausts kind of cut out. Not to mention its real hesitant and it does ths 3 out of 4 times I am driving it, its weird. What could this be?

sounds like you may have a bad vacuum leak...pop the hood and check for old vacuum lines running into your upper intake and all others like the vac trees in your fenders. If you are getting a bad idle like you have a cam, that usually means a line is leaking somewhere. Look around under the hood and listen for anything that sounds like air blowing out of a line.

You can do the salt and pepper check. It the wires on the right side of the engine bay that look like salt and pepper shakers (ten pins). The pins over time get lose. You can go to ford muscles web site and find out everything you neede to know about it. GOOD LUCK :headbang:

also how old are the plugs and wires? when was the last time you cleaned the maf and iac? gotta start with a good base before trying to troubleshoot

cleaning the iac, throttle body, maf, resetting the tps, that's all covered in that link up there. I would check for vacuum leaks and go through all of these things... I would almost bet these will solve your idle issue.
