Ok so sometimes when i stop my car will drop rpm's and then stall. Sometimes tho it will rush back up from like 200 rpm, my idle is set at 1000 rpm. And the other day i was making a turn onto another road and my car just stalled in the middle of the turn. Anyone have any ideas. I have cleaned the MAF and the IAC.

Car is a 95 Cobra and has the following mods that could possibly affect this problem - cai, headers, x pipe, X-cam, crane ignition coil, ford racing plugs and wires.

The car usually runs great and has been Dyno tuned, and it doesnt always do it when stopping only sometimes

anyone have any ideas ??

replaced the fuel filter lately?

throttle body plugged up?

does it only do it when the engine's warmed up? only when cold?

Asylum839

fuel filter replaced about a month ago, no TB leaks, and it does it when its warm or cold its not biased to one temperature lol

is there a bunch of gunk/carbon built up on the walls of the throttle body though? and on the butterfly inside? that causes idle problems.

have you checked your tps voltage?

what kinda fuel psi do you have?

Asylum839

tps voltage is good, fuel pressure is good, and only thing i can think of that you mention is i ran out of carb cleaner before i got a chance to spray the throttle body, the butterfly is clean, but the rest of the TB is pretty dirty, i really didnt think it would affect the idle like that tho..

it affects some engines more than others. if you got most of the throttle body clean, then it shouldn't be your problem. could be though

i'm trying to think of what else it could be here..

haha i know tell me about it man, its got me going crazy!!

Is it a stick? And does it happen when you slow/brake with the clutch in? If so I would look into the IAC on the t-body.
