I would replace the wires and hold off on the 255 b/c you'll need an afpr to go w/ it.

 

okay so now ive changed plugs, wires, fuel filter, air filter, Bov, and seafoamed for the injectors... still fuel cut/missing, idk the difference im thinking maybe coil packs??? it only does it at around 2-4.5k rpm. how do i check coil packs without replacing them cuz i dont really have the money to be replacing good parts

 

My Evo was boost cutting early in the RPMs due to a small leak from the trottle body shaft seals being hardend over time and leaking. Common problem on DSMs amd other cars actually and it was a $17 fix. That is a cheap place to start
