calling al tuning gurus, code 368

[Slow 95 TSI]

Ok my Talon has been running pretty good since I get the afc working right. But today it started running like chit again. I was able to smooth it out with the afc at least.

The trouble first started when I installed the afc & the 650cc's It would trip a code 368.
( fuel trim malfunction bank 1 ) it was good for a while now today I got the 368 like 6 times. I was looking at my 02 sensors and #1 acts dead most of the time reading 0.00 and #2 reads 0.96 most of the time. Assuming the way the numbers look the car should be on the lean side but when it acts up I get the black smoke like it's running real fat.

What gives? Anyone have any ideas?

I am thinking my #1 sensor took a chit and it keeps f'ing up my readings.

Thanks in advance for any help you can give me.

Sure enough it was the #1 sensor. I installed the #1 out of my parts car and hooked up my scan tool to it and that one was alive. I took the car out and drove it around in test drive mode and set the afc while watching the scanner.
It works real good again.

That's what I would have guessed...
But I'm glad you got it working.
