1. The scanner gave me the codes indicated what was wrong. It read to me
P1123 and
P1125.
2. I found the meaning to those codes,I beleive it was;
"P1123=( Oxygen Sensing Adaptation Area 1 (Cylinders 1 - 3) - Lean Threshold)"
"P1125=( Oxygen Sensing Adaptation Area 2 (Cyclinger 4 - 6) - Lean Threshold)"
3. Time to troubleshoot. Searched every archive I could,talked to MNBoxster(he was dead on),called around some indie Porsche shops. As soon I let people know I had a K & N air filter from the previous owner they said to change the MAF.
4. Bought a new MAF and walla! All was good again!
The codes only point to whats rich,lean,misfiring etc. They don't say specifically what is causing the issues. Thats what the
search and
archives are for. Good luck with all those codes.
