mustnglvr

Yeah my everything has been swapped and im tryin to figure out which one of these is causing my problems

Ecstasy

whats your problem?

mustnglvr

the car ran fine when i finished it about 3 months ago but its got no power lately its running fine just no power anymore. sometimes when your driven and let off the gas the throttle will seem to stay in the same position and not slow down, when you start it up it surges to about three grand and goes back down to less than 1 grand. But the main problem is it has no power anymore, I hate troubleshooting electronics and am lost this is also my first stang

Ecstasy

what all did you change, post your combo list or what you have done to it, and well start troubleshooting it from there.

306, stock maf, stock inj, cobra intake, tremec 5 speed,3.73. i havent got around to changing the maf injectors and tb. When i first finished, it would beat an 01 ls1 ss not i dont think i could hang with a stock mustang

holy, when you upgrade your intake and all that the most overlooked upgrade is your fuel system, you should atleast upgrade to a 155lph, & get an adj. fpr, whens the last time you did a tune-up and even so, check all your plug wires & spark plugs, you have got to update your maf & tb. thats what is making it drag which i know you feel going from 1st - 2nd 2nd - 3rd. until your rpms get to around 2500 right?

Already have a 190 fuel pump and fuel pressure regulator with brand new plugs and wires. whats bothering me is it ran fine when i finished, it just quit running strong one day and the trottle started to act like it was stickin at the same time thats why im thinkin its a sensor problem

unhook your bat for about 30 mins, both terminals, thatll reset your computer, and then run the codes again, but write the whole information when you look it up.
