So i just did a few new things to the trac and now im getting trouble codes 25 and 26, engine lean and engine rich. I got a full exhaust, started running 12lbs of boost, got new wires, and switched to copper plugs. I was wondering if im getting these codes ecause im running a colder plug? Do i need to run bigger injectors or a bigger fuel pump to even out the colder plugs or should i switch back to the NGK platinums i was running before?
