Please help
I have an 89 mustang 5.0 manual. Here recently it's been losing power. When I crank it, it idles fine, even if I rev it. Once I actually get moving it is sputtering. If I accele slowly it will move a little better. If I hold it wide open it backfires sometimes but will not go any faster. I changed fuel pump, filter , cleaned out mad and tps. Any help please

KOEO/KOER check for codes.
Check fuel pressure at the rail
When was the last time the car had a full tune up ? Plugs wires cap rotor air filter ?
It could be a faulty coil, faulty TFI module, faulty PIP.

Welcome to the forum, if you don't know what dawson is talking about, use the search feature and do a little reading. There's a ton of info on this site to dig thru and it's all been covered before. Good luck

Like daswon said. Sounds like your dizzy might be the issue. I had this problem before. Bad pip more likely. Word of advice, if you do buy a new dizzy make sure its new NOT a rebuilt/remand. They are garbage.
