i have a 93 wrx had a coil pack problem and have changed it and sorted out this problem now have the car running on all 4 again.........

but since conecting it all back up i have developed anothe rproblem and not sure what i have done???

the car has kimited boost and seems to be over fueling hence its popping and banging all over the place at times the exhaust over heating light comes on???

i thought it could of been a split hose so have renewed them all with samco hoses it has improved but not a lot

has anyone got any ideas???????????

 

did you debug the exu for error codes ??

may need a reset ???

 

Did reset ECU by disconnecting battery for a bit, currently in process of doing this again now as just fitted new O2 sensor and replaced a coil lead.

Is this the correct way to re-set a my93 import???
