Re: 5.0 mustang low RPM miss
Any mods?
If you have aftermarket rockers, adjustment could be out, you could be losing compression? just a guess.
Also, sounds ignition related, but it could be a weak fuel pump, you need to be sure your getting fuel pressure.
And that you dont have a defected coil, even if it's new.
Check engine grounds, and see if you can run a code scanner, and pull codes. could be a number of things, clean the maf, i dont care if it's new, and make sure all injectors are squirting.
good luck..
