UPDATE
Thought id keep you all in the picture, god forbid this happens to any of you.
The car has been at Envy for 5/6 weeks and I think theyve checked every electrical componant in the bloody thing and doesnt seem to be any of them.
They have discovered that when you turn the car over to try and start it then take the plugs out, if you rock the car you can see the petrol sloshing around in the plug holes, (not good).
So its overfueling, not underfueling.
fuel pump and petrol has now been changed and all lines cleaned out. When they took the intake off they found a swimmingpool of petrol inside the bottom of the intake. So finger seems to be pointing to the injectors are sticking open when firing. nerxt job is to test the injectors and rebuild the intake and hopefully this will cure the problem.
I need to phone him next Thurs now so hopefully ill have some good news. But up til them im gona have to drive me misus's Audi TT. Its not a bad car but it aint a SUPRA thats for sure.
