I have a 1999 mustang gt. It just starte feeling like it wants to shut off when im driving or still, it has the check engine light, but it has been having that since I put a no cat h-pipe.Idleing is also becoming some what of a problem when the car begins to stall. Any ideas?

HAVE YOU EVER RAN OUTTA GAS??, I WOULD CHANGE THE FUEL FILTER AND ALSO CHECK THE AIR FILTER A DIRTY ONE WILL MAKE IT RUN LIKE WHAT YOUR DESCRIBING.. ALSO, THE AIC VALVE SOMETIMES GETS CARBON BUILDBUILD AND CAN BE GLITCHING..

Maybe clean your MAF sensor as well.

how many miles on your car? last tune-up? clean IAC and MAF. also you might want to get the car scanned to see what codes you have.

i do oil change every 3000 i guess ima clean the MAF tommorow to see what happens. The only code i have is for BANK 2, oxygen sensor, but that is because of my h-pipe and I have MILs on the rear sensors should I put them on the top ones too?

Your going to throw codes regardless for the h-pipe. MIL eliminators are hit or miss. Best way to shut off the CEL for 02's are a tune. Your IAC is located right next to your throttle body. Unbolt the 2 screws and clean it out. Also you could have a secondary mis fire in the wires if you haven't replaced them. A mis-fire in the wires won't throw a code. Replace the fuel filter and go from there.

+1 on the fuel filter. I was losing MPh and blowing head gasket's and it turned out to be the fuel filter ![[Frown]](frown.gif) . Plus it should only be 10 -20 buck's and is pretty easy to install.
