My wife's 2001 2.0 has been giving me a workout. Just a little history. The Beetle was calling out bad cam position sensor and it also was losing radiator fluid. So I decided to pull the head and replace the headgasket. Replaced the water pump and timing belt, cam position sensor and tensioner. Put the car back together and it ran like a champ the first day. The next day it crapped out and had it towed home. Got on the board and got some help and it was determined that an unrelated problem occurred.
A guy said try cleaning the MAF. I did and the car ran beautifully for a couple weeks and started calling out P0171. I bought a new MAF, installed it yesterday, the car ran good and I gave it back to the wife. After 20 miles or so, it started calling out P0171 - system too lean - bank1.
Not sure what the logical order of diagnosing should be. I replaced the fuel filter about a month ago.
I just test drove it and it seemed a little confused at idle and then straightened out. I took it for a spin and it just doesn't seem to have the acceleration that it used to have. I unplugged the MAF, drove a couple of miles and I think it runs the same without the MAF which I understand makes the computer run on default values.
I am suspicious about the MAF connector. It looks fine, just a hunch. It seems that I am near the problem, just can't put my finger on it.
Don't know where to go from here?
