Hi all! Finally at my wits end with this car. Ever since I got it, it has always run a little rich, has progressively gotten worse. When I first got it, had the usual Cam sensor codes. Swapped out for a VDO one and never saw it back...until about a month ago. Codes I get are for Cam sensor Maf sensor Both very intermittent, Typically when these codes pop up, I also see on INPA that the o2 sensor heaters are not doing anything, and cannot view fuel trims.
