Default Need help!
Put my gibson exhaust on and swapped the header gaskets now when I drive down the road and accelerate it sounds like I'm missing.? I have a ses light but haven't read it yet. I haven't retuned for the exhaust yet but my original tune I cancelled all emission codes.(rear O2s,egr,cats).

Get the CEL identified...

Check all your spark plug wires and o2 sensor connections.

Read the codes I have a random misfire and bank one o2 sensor. I still believe it's fuel pump related
