but really all you have too do is buy A Can of compressed air for like dirty computers. the way A Mass air flow sensor fails is two ways: either the Air Filter gets dirty and then it sucks the dirt on the mass air flow sensor causing it too read incorrectly, or you just knocked the cable loose. that's so it can measure how much air the engine is sucking in so it can know how much fuel too put into the engine. well in A Mass Air flow sensor there is A Really tiny, tiny, tiny, tiny comb-shaped wire in the sensor. well boy sit down and grab A Cup of tea cause i'm gonna tell you how too fix it with just A Can of air, but first let me explain how that electrical thingy works. Well it looks too me you do have A Bad Mass air flow sensor. I still don't believe what the dealer said so I'll check with another shop soon. I'm only talking about 3500 rpm uphill and 3500 - 4000 on the downhill. Well every direction I go is up mountain passes which require higher RPM to keep things moving and engine braking on the downhills to save the brakes. They also told me this was common on the 4 cyl.? especially when driving at higher RPM's. So I bring it in again and they checked the PCV and said everything looked fine. I then phoned the dealer and they said the PCV system was probably plugged and to bring the car in again. Oddly enough this didn't throw any codes but my fuel mileage was lower than normal and quite a lot of soot in the exhaust tip. So I removed all the air intake pipes and MAF sensor and cleaned them. I found this out when I changed the air filter and found oil in the intake pipe and up into the TB.
Something to watch for is the possibility of oil migration up through the throttle body and into the air intake system and coating the MAF sensor.
