Well I have not been active for pretty much 2 years due to a bad ilness and the Subaru has just lay there all that time (until a few weekends ago) . I never got around to sorting out the misfire before I was ill.
The car is an Impreza 1997 UK Turbo 2000
But now I am fit again, I have been working on the car. I have now fitted (some fitted before ilness) new coilpack, HT leads, Plugs, MAF, Injectors, Timing belt kit, Fuel filter , Had inlet manifold off and resealed. I also did a compression test and all cylinders and showing all close to 150 psi.
I still have the misfire at around 1200rpm and the back firing and not as quick as the car should be.
The car has a full decat stanless exhaust system and I am unsure it it ever had a daughter board fitted to the ECU.
My question is... Will I be able to swap the ECU for a direct replacement for that model and year ? and is it possible for that ECU to cause problems with a misfire in one cylinder and also a rich mixture on the other three ?
I have managed to aquire an 8s ecu, but how will that go with my immobiliser fob. Now I know why I was ill lol.
Best wishes
Johnny
