RE: Fault code P1128 gone, but now P0102

As Mike@DTH said, make sure the MAF is plugged in. Also check
all vacuum lines for leaks.

Similar problem..

I have two codes p0102 and p1128...i checked for vac leaks, cleaned the maf and confirmed its working....

the light LITERALLY came on 20 seconds after i put fuel system cleaner in the tank. Anyone know if this stuff could have caused the codes???

Clear the codes and see if they return.
