I just bought myself a 1994 mustang gt with a 5.0. The car has an intake, ford motorsport wires and an msd ingniton thing that i have no idea if it works. The car has a whoping 239,000 miles its a stick. The car had a rough idle so i cleaned the maf and iat sensor, it got better. The car need new plugs the last owner gave me 8 new bosch plugs, i need any tips i can have on how to change it. The car has been tuned to run on premium the last owner was part of a dyno tuning garage. I beat a cobalt SS yesterday it was my cousin we did a 30 mph pull he got a little gain in the start but by 80 i was a car length ahead of him. Tell me any tips i can have with this car thanx i apreciate it. I just put seafoam in the gas tank this morning.

Cobalt SS...thats a big difference. I think those are supercharged with around 205hp and 200ft-lb. Thats actually not too bad out of a tired SN-95. Do a real good tune up on her. New plugs, cap, rotor, check the resistance on those wires. New fuel filter, run some injector cleaner through there. Make sure everything is up to snuff then treat her nice.

Ya it is the supercharged version, when he got it he did a 14.88 with 2000 miles on the clock, i think my stang is running a bit rich i think i have a fuel pressure regulator does that do anything to lean it out a bit?

If that car ran a 14.88 that doesn't sound too bad for an SN95 with that many miles on it.

Are those Bosch plugs copper or platinum? If they're the plats I'd get some cheapie Autolite copper core plugs instead. 5.0's seem to do better with regular old copper plugs.

For the rest of your tune up... do a cap & rotor, plug wires, fuel filter, PCV valve and screen, oil change if it's due, with that many miles I'd probably replace all of the fluids if it hasn't been done in a while. Seafom is good stuff, I haven't tried putting it in the gas tank, I'd put some in through a vaccum line under the hood before your oil change. That's how most of us here use it.

If you have an adjustable FPR then yes you can turn down the fuel pressure a little. Do you have a fuel pressure gauge on the fuel rail as well? You'll need a gauge in order to adjust it.

they are platnums i dont want to change the plugs yet the car is running pig rich and i dont want to foul any new plugs, sometimes the engine light comes on but i dont know how to check it, when it usually does i smell the gas smell, and the car has a hard time starting but when it does i need to let it run for like 2-3 minutes before i can drive it or it will jerk like there is no end. It runs fine but i need to figure out why its runing so rich 130 miles to a tank of gas is not fun lol!
