- Wrong MAFS? Verify part number
- Fuel lines backwards? - Big vacuum leak? (use a boost gauge) - Injectors stuck flooding engine? (check oil for fuel smell) - Throttle not opening or idle control not working? - Unplug coils 1 by 1 while running see if any 1 does NOT make it worse - could be bad - Same thing with injectors - unplug while running 1 by 1, all should make it run worse Just some basics Good luck |

pee on it.
you need to check things like fuel pressure, both KOER and KOEO, if you have an aftermarket FPR, make sure the diaphragm isn't leaking,
