CEL P0170 and P0171
Just finished my swap from a 1996 GSR to a 2000 GSR, both OBD2, and I'm throwing two engine codes: P0170 for lean fuel system, and P0171 for lean fuel trim.
What baffles me is, this engine ran great with no CELs in the 96 chassis and now it's lean all of a sudden.
With the swap, I changed the intake and exhaust back to stock and put a stage 2 clutch in.
Any ideas on what could cause the codes?
