OK so the light is still on...the car is still running great, and idles smooth after a couple days of having the light on. so i am guessing this is not a huge deal to the extent of which i wouldn't be able to drive the car. I have been thinking about how when I clear the code with my handheld, it comes back, so that means that the engine is definitely finding a fault that is reoccurring. So at this point, I want to find that "open gas tank vent valve" any body know where this is on the car? is this something I can get to without dropping the fuel tank? Can I service this? - Is there any thing special I should consider when cleaning my MAF, or at this point, now that we know what the code is would a faulty MAF produce this code? I feel like we are getting close, thanks for the help.
