I have a 2001 vw beetle. 2.0l AZG Engine with automatic transmission. It's been having many problems. The last shop just diagnosed it with 8 codes. 17574 Long term Fuel Trim Additive Air Bank 1 Range 2 Rich (P1166)16684 Random Misfire (P0301)16685 Cylinder #1 Misfire (P0301)16705 Engine RPM Sensor G-28 Not a Plausable Signal (P0321)16688 Cyliner #4 Misfire (P0304)16686 Cylinder #2 Misfire (P0302)17553 MAS G-70 Short To Plus (P1145)17549 Load Calculation Cross Check Implausable Value (P1141)It has been idling rough and sometimes dying when it comes to a stop. I replaced the plugs, new air filter, new timing belt, new fuel filter and didn't fix it. Took it to the dealer they said the oil dipstick was broke so that was causing a vaccum leak. That didn't fix it took it back and they said it needed the MAF sensor replaced. Bought a remanufactured one from Autozone Part Number 74-10052. When I put that in then it still wasn't running quite right and then it started to rev really high before shifting to me like there is a pressure problem or something just not telling it to shift. It always seems to shift just at higher than normal RPM's and it shifts pretty hard. All the codes listed above were from a different mechanic shop. They basically said it needed a new transmission, but I'm thinking maybe just a valve body or could the MAF be bad and causing alot of other issues. Any suggestions. They quoted $4000 to rebuild the transmission so I would like a few other opinions. Thanks in advance.

Welcome to Just Answer!!!Ok the cutting out issue is related to fault # XXXXX which this issue is very common you will need a new crank sensor , did the reving up issue start after the auto zone mass air flow sensor replacement?

Yes the reving up issue seemed to start after the autozone replacement. It may have been there before, but I seem to drive the car much harder than my girlfriend does so I maybe just noticed it more. I've heard about the crank sensor issue, I was wondering if that was the issue, just got to the point of being tired of throwing money at it.
Yes the crank sensor issue will cause the stalling out , now did you erase the faults after replacing the mass air flow sensor ??
I did pull the cables off the battery and clear the computer after I put the MAF sensor in. Then I just picked it up today from the shop and they must have cleared them with their scanner because the Check Engine Light is off currently. After I cleared it the first time, it did come back on after a day or two of driving. I haven't driven it enough yet from the mechanic shop, but I did notice the EPC light coming on and going off a couple of times.
Taking the cables off the battery does not clear the codes from the computer only way to do this is using a scan tool, even if the light is off does not mean they are not stored in the ecm . The epc light could still indicate a issue with the mass air flow sensor i recommend you replace it with a vw mass air flow not aftermarket and also replace the crank sensor and you should be better also have the codes cleared this should help out .
I'll get that stuff replaced and let you know the results. Thanks for the help so far!
