Ok, i got the DPFI to MPFI swap on my 91 civic hatch and it runs fine but the damn CEL pops on once the car warms up but it throws no code at me. i thought maybe the ECU was bad but i popped in the PG7 and same thing.what is it? plus once the car warms up and if im driving with steady gas theres no light, but when i come to a stop and then start moving again it pops on. any ideas?
