  1. does your engine symbol amber fault light go on when ignition is switch on, then go off once starts up? ——— Yes, engine light comes on then goes off as it should did it do this from day you bought it? ———yes it has done have you fitted exhuast or induction to it? ——— the car has an exhaust, front mount Intercooler, “induction kit”, silicone hoses has the car been remapped? not sure if that year can be!! ——— from research it appears it CAN be remappped but I don’t believe it has been have you any fault ECU codes? ——— had a MAF fault code, new GENUINE MAF fitted and code cleared most common issues are air leaks have you an atmosperic dump valve. ——— yes, due to front mount Intercooler check all vacuum pipes for cracks/leaks check all boost pipes for leaks & splits swop 2 injectors two other sensors can play up, the temperature sensor for ECU, not the one for gauge. can run like choke fully on. okay ish when very cold but much worse when warm and the exhaust sensor, runs closed loop with no throttle and correct burn from exhaust sensor. when throttle put down open loop, burn controlled by Program Map.
  2. Good evening, I have recently purchased an Impreza STI V5 but it has some running issues. Hot or cold it appears to be running on number 1+3 cylinders on low rpm, if you rev through this then it seems to “clear” whilst the revs are high. It does splutter getting up there though. I have tried new plugs, new HT leads, new MAF and new coil. I have compression tested and all seems fine. any ideas? cheers
