I hate to bump such an old thread, but a lot of the threads across differing forums end up without anything conclusive.

I too have this code and similar symptoms. I've currently got an OVP sensor en route from a friend to test with, and understand the wiring harness can be shoddy/failed...but I'm avoiding paying for one before going much further.

Car runs fine when cold/start up, but does have excess fuel smell. As soon as it comes into operating temp it runs mostly fine at speed, but low speed hesitation and wonky idle when coming to stop lights. Yes I can drive around it, but don't want to find myself stranded either.
