Picked up the car tonight from Hyper Sports and Racing and problems gone. Turned out to be a faulty wire between the Traction control and ECU. Took them ages to find it though and they were getting pretty frustrated themselves with it. Anyway, its running sweet now and was a very enjoyable drive home.

 

Thanks a million to everyone that has had some input into this thread and thanks for being patient with my endless supply of questions that ive pestered you with. :respekt: :grouphug: I owe you all a :friday:

You are not alone.

Often similar problems are due to corroded/dodgy connections in looms, especially if aftermarkets bits have been spliced.

 

I've even sold a car in frustration when I couldn't find the source of mysterious misfires after changing everything in the ignition and fuelling systems. The only thing left original was the ECU loom, and I wasn't prepared to rewire that one. Anectodal evidence suggests that those *do* go wrong after 10years due to cheap materials used by the factory (Vauxhall, quality....)

Really please for you matey! And you've even got enought left to get to mascrat :) Just out of intrested to they put it back on the dyno for tuning?

 

It did go on the dyno for diagnostic purposes but didnt need any tuning, they said it was running fine. Dropped off my bumper tonight for paint so hopefully should have that on for Mascrat as well :D
