My friend says he's tried askin at TCstangs but no one gave him an answer on what it could be. Anywas he has a 1995(maybe 94) GT 5.0 mustang with basic mods, intakem, exhuast, underdrive pulleys etc..
A few weeks ago he went and changed out most of the ignition stuff, wires, plugs, distrbuter thing, and it ran fine for a day or two, but now the car stumbles/backfires.
From what I've seen if you sit in netrual and try revving it, it will rev up to ~4k and then it starts to stumble and backfire and it can't go any higher, I guess this is how it acts also while driving.
I know this is a DSM board but, any ideas?
