Just throwing this out there after initial checks. This code re-occurs almost immediately after erasing. The code is for incorrect comparison between the throttle valve opening angle and the intake pipe pressure (pressure too high). I pressure "smoke tested" the intake system - no leaks found. There is (what i consider) excessive oil deposits in the intake tubing and there is what appears to be some oil smoke upon start-up. I have read elsewhere that apparently these same issues had happened to another identical car and the problem was found to be a cracked cylinder head! Any thoughts on this??
