I'm picking up a Bora V6 4motion next week for a really good price because it's got a problem no-one seems to know how to fix. It has no power. Idles nice and sounds sweet when you rev it in neutral but start to drive off and the accelerator pedal may as well be disconnected for all the good it does. It does accelerate but very slowly. The local auto electrician plugged it into his scanner which said the oxygen sensor was faulty and killed the ECU. How they came to that conclusion I don't know - how can a signal from a sensor damage a ECU??? Anyway, both were replaced and didn't fix the problem. On a short test drive I disconnected the MAF but it made no difference, didn't even make it worse. I didn't check to see if the limp home light was on but there wasn't any buzzer sound. I'll know more when I get the car home but what should I start looking for?
