It sets both a P0422 & P0432. First off I was advised by the VW gurus to change both #2 O2 sensors since it has over 100K on it. So $330 later I still have the same codes. The O2's both behave alike, when they warm up the voltage drops to around .060-.100V. Both #1 O2's are behaving correctly and I have no LT or ST fuel trim corrections. This suggests the engine is running correctly and not in a lean condition. I must be getting fresh air in both of the exhaust pipes between the manifolds and cats. The previous owner had replaced the flex pipes just before the cats. Whoever welded them on couldn't reach about 1" on the top side. I installed a submarine patch on one side yesterday evening and reset the codes. I'm not to confident though. When I looked at the data, the O2's both dropped to a low voltage as soon as they warmed up.
I've also tried the anti-fouler modification to the O2's without any change. I'm begining to wonder if the guts have been knocked out of the cats. But I've owned and drove the car for 6 months before the light came on.cratchhe:
"Brutus" is driving good. I finally replaced the sector shaft seal to stop my PS leak. Now to put my spare carb together and fix the electric choke.
Back to your thread! Nice trailer! Are you going to brace the tongue any more?
