I don't know if or which cylinder misfiring or whether its random. I agree that there has to be a fuel delivery problem since all my problems started when I had the IP delivery O rings and seals replaced. I'm considering having the injectors tested.


When I increase the idle slightly, it still runs rough and it's noticeable until the RPMs are above approx 1500, unless, as I have mentioned before, the A/C compressor is running or the car is in drive.

I took it out for a drive this evening which included some hard acceleration. I was thinking how well it runs and then another problem popped up. It overheated and non of the electric windows close now. I think at the very least I have to replace the thermostat. What is really strange is that the windows won't close.

As for the EGR, I do notice some dark staining around from the cross under pipe from the turbo to the intake manifold. Next time I have the manifold off, I will take a closer look at the EGR.
