Gentlemen,

I am new to the forum and would appreciate any advice you guys may have. I have a 97 with 30,000 miles. It runs perfect all day long but when I start driving aggressive (tach around 6,000) the CEL comes on. The code was a misfire left bank 1 & 3 if I am not mistaken. All service have been completed by Porsche since day one. The Porsche dealer thought it was the airflow sensor so I replaced it. Porsche checked the hoses on the emmissions but did not find anything. I will say that the air pump can be heard on cold starts. It seems to be as little loud but I have nothing to compare it to. Any help or suggestions would be appreciated. Thanks in advance.
