Hey Ken, I see there's been a lot of suggestions so far, and it does seem like it is a slipping trans, so did that TSB I listed for CVT issues in my previous post turn up any answers? I saw that you said the TSB for the 101 code has been done already, so that essentially eliminates that path. I read back through your original post and there's some information I would like to know about. Have you been able to recheck the a/f ratio and rear O2 sensor values under WOT throttle? I know you said in a post that you couldn't remember the value of the rear sensor, but it would really help to know if those sensors respond properly and show full rich under WOT. The incorrect MAF reading may falsely skew the fuel calculation, so that check may have to be done with the MAF unplugged. I'm asking that because I want to rule out a fuel volume issue, as I've been humbled by a volume issue in the past. Pressure doesn't equate to adequate flow, and that burned me really bad once.
