I have a 96 Golf, 2.0L gas engine, that occasionally loses power and stalls,
usually in stop & go traffic. It is throwing the code P0134, which is for
an oxygen sensor not responding.
Both O2 sensors have been replaced twice in the past year. The car has
received new wires, plugs, distributor cap, etc. in recent years.
The first mechanic kept changing the O2 sensors. The second mechanic tried
a new Mass Air Flow sensor, but same result. He tested the O2 sensors and
found them to be fine. He found good fuel pressure. He indicated that the
computer was getting good inputs but providing bad outputs. So he
recommended changing the computer. We had him put a used computer in the
car. It worked fine for a day or two, but the car is once again behaving
Has anyone else had this problem? What are the mechanics missing? '
