baz i was talking about the green light on the ecu. yesterday i think i found the dial you were talking about. its on the ecu right? it is currently turned all the way anticlockwise. what's it for? when i switch off and restart both lights are out. only after i get the stumble then it flashes a couple times then remains on continuously until i switch off again.
i realised that my problem only occurs when the engine boosts to 10-11 psi either on s/c or turbo. it feels like the engine is stumbling. once i easy off the throttle and the boost drops below 10 psi it pulls smoothly.
question what boost is the s/c supposed to make max and turbo max on a stock engine?
beginning to wonder about the fuel pressure regulator and wastegate. think either could be the problem?
