EOBD Warning Light - V6 - hard accelleration
Help from those who know needed.
The EOBD light comes on when I accelerate hard in my GTV P2 V6 24v. At the same time I get an immediate reduction in power - it feels like a limiter has cut in. The light then stays on for about 24 hours, then stays off when I start the car, until the next time I accelerate hard. Other than at the point the light comes on there seems to be no loss of power or affect on fuel consumption (although I could be wrong about this - I've not had the car for very long).
I've taken this to a good garage, who say they replaced the MAF, but it's still happening...
The only other clue is that a few services ago (before I owned the car) a mechanic has noted on the paperwork that the air filter was VERY dirty when it was replaced.
Thanks in advance.
