Engine/Transmission (1998.5 - 2002) Codes

[nfox]

I just bought a 02 24v and i have three codes and was wondering what they are, 122, 234, 1693? It ran really good at first and now it is really doggy? Any suggestions?

You can find the codes in the 911 forum.

The 122; APS low voltage, is probably the one. There was a set of instructions floating around that discribed the procedure for calibration. I'm too tired to look it up, do a search for "APS calibration".
