I got car back from protosport last Friday, and John was awesome. I was chasing p1126/28 codes, as threads I have posted stated this is everything done to the car in last 600 miles:
New MAF
New plugs
New 997 coil packs
New oil cap seal
Vac leaks none
Exhaust leak found and repaired
Pressure tested, passed.
John was second mechanic on car, had her for week, drove her over 100 miles, and I drove her 60 up there and 60 back(I had taken picture of scan, and CEL light- but cleared codes. John was scratching head...the p1126/28 never came back. I drove the car another 300 miles since, today on way home idle skipped a little 5 miles after startup CEL....durametric scan, p1133 Porsche fault code 358!!!
2 things, car drives awesome, and strong...I am not posting to bash, just looking for some input.
Iirc macster suggested on renn list to replace O2's when I listed what was
done and codes kept coming back.
Any ideas? I just want own her for a solid month w/o a code.

that looks to be a air leak or fuel delivery problem to one bank. could be leaking O-ring on injector/s. or bad injector. GL

 

Ty for the response

 

I have met both the past owner of your car and John and feel you are in good hands with both.. I chased that same code on my car and never found it. I took the motor down and did some head work and when the motor went back in the code was gone. Know idea what it was but I did change injectors at same time too.. GL

 

both good guys.

 

I have had my 993 hypertuned with Protosport and they are currently doing the same with my 996, and I recommend them to anyone who asks me for tuning advice. If you remain patient, they will serve you well.

 

I am learning to be patient, .... I like John @ Protosport. I did log MAF last night, and the as stated MAF only has 600 miles on it...read fine. The search continues.
