why are they so expensive? one of my rear sensors occasionally reads high voltage. i can clear it out and it doesnt come back for a while. my gas mileage is not so great though.

 

also, any one ever experiment with using regular gas in a vq engine?

I got my 02 used w/ 47K miles on it and used "premium" the first tank I went through. Next tank I used Mid-grade and then regular the next. A million tanks later, I still use regular and it's just fine...no detonation. Then again, that's what knock sensors are for. I AM going to get a fuel system cleaning in the near future though.

Maybe I'm totally nuts, but the Pathy seems to get better mileage w/ regular gas?
