Hello guys,
So recently I had my Fore tripple pump fuel system installed along with ID1300x and some boostane on 91oct
As data logging was being done everything seem to be running well.
After almost being done with tuning and data logging the car started to misfire and throw codes P0300 P0307 P0308.
I went ahead and swapped to some new NKG 6510 gapped at 0.028 and still had the same problems. Tuner sais everything looks good and the misfiring seems to be mechanical.
Can a bad cat cause misfiring?
Mods are
- Built 5.2L motor 5k miles
- Stage 2 whipple
- Fore tripple pump fuel system
- ID1300x
- NGK 6510 gapped at 0.028
- 91 octane with a 32oz bottle of boostane
- Stock headers
- Stock resonators
- Stock cats (40k Miles)
- Roush quad tip exhaust
