I got a 2000 Mustang Gt and every once in while when coming to a stop the rpm's drop low and sometimes it stalls not all the time though. I took it to a Ford dealer and had test ran and it came back that the IAC was bad, so i replaced it with a new one. Still same problem i also replaced the TPS, PVC, took throttle body off and cleaned it throughly, still does it. Can someone please help me out everyone says the same thing IAC but it isnt. No check engine light is on and also i cleaned off the MAF sensor to. New o2 sensors about a year ago spark plugs all clean cant hear any air leaks and sealed every place possible. Thank You

Me and my buddy did tat it was unplugged for a hour pumped the brakes to drain it totally and reset the trim still same thing.

Pretty much next to the spark plugs. You will see the fuel rails going to each injector. You can have them cleaned or run a can of BG-44 K through the gas. Thatshould help.

Shell V Power does tat doesnt it

sprostang

Yeah but not as good.

immencedata

ok what is the brand or is that what it is called

sprostang

Thats what it is. BG-44 K. Search google for it. It`s $20 per can.
Chances are you mayhave another problem though but this should help out. When did you change your spark plugs and fuel filter last??
