Question

Tried 3 coils, plugs,plug wires, new fuel filter, air filter,& Maf sensor. I know some stuff is not with issue but I put all that's new down

Answer 1

if you replaced the coil and it did not fix the issue. You should check to see what voltage you are getting on the other coils and compare it to coil #1 

- Ignition Coil 1 harness is open or shorted
- Ignition Coil 1 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
