[quote="efxr6wagon"]Here are the instructions for pulling codes (from my Gregorys manual):

Has the car been ran on gas? Valve recession will cause these sypmtoms

No, only petrol

I had a similar problem.
Codes checked and all ok.
Removed the cam phase sensor plug and all seems well.
It has done this before, however, and am going for another big drive today to see how it goes...but it did the last trips without issue, which has not happened before, so I'm hoping the problem is gone.
Oh, it idles much better now, too.
I've spent nearly $800 on coils, leads, plugs, mechanics looking at it...yet it took 20 mins to pull the plug, tape it up, to fix the problem.
I was told t do this at the very beginning, but didn't....
If it comes back, I'll get the injectors looked at.
