Oh, I recall seeing your car parked next to mine a few times... it's that
pukey green one, right??

Seriously.... a few particulars would help... year. model, engine size....
we are even assuning that this code is a "P" code and doesn't have a "U",
"C" or "B" prefix?

Others may go furbling for you but there are enough instances of "near"
pattern failures that can happen in particular production runs..... there
are year to year changes that may make a particular action or test
inappropriate.

Without some basic information, it's going to be a crap shoot....

Getting this fault code car has rough idle but drives great at high
speed . code points to cam valve sensor to advance does this mean the
sensor is bad or is there and actual timing problem. Help
