So, for the last few months I've been experiencing much more popping exhaust than usual, and also about 20% increased fuel consumption.<br>So, I finally decided to clean the MAF with CRC MAF cleaner.<p>When I took the sensor out, I saw something was clearly missing. I didn't take a picture of it so here's one borrowed from the net:<p><IMG SRC="http://img36.imageshack.us/img36/7448/mafh.jpg" BORDER="0"><p>The thermistor was gone. So, I figured the computer thinks it's freezing cold weather all the time, and feeds the engine a richer mixture, am I correct?<p>Getting a new MAF tomorrow, hope it fixes the issue. I tried to get just a new thermistor, but it was pretty much impossible. And at Bosch service I got laughed at, so I had to buy the whole thing <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> <p>Just FYI, if you happen to experience similar symptoms. In hot weather areas it could be even worse.<br>It's easy to check, if you can open those tamper-proof screws on the MAF.
