My 02 2.7 has the CEL coming on and off with different fueling( so it seems ) the wife gets gas when ever its needed and not always at the same gas station,..But in the same town Tucson,az ...So maybe the additives or maybe gas cap..?? the CEL is on more than off even with 1 02 cable changed out,I think its on 60% of the time ??? Thanks Frank
I have not looked at the old one yet but I did pick up a new one from Porsche for 20.00,..sure hope that's it..I bought all new O2 sensors but I cant get the connectors off . Thanks Frank
Any muffler shop can swap your sensors. Doesn't need to be a Porsche specialist at their rates. Just takes a bit of lift time to let the exhaust cool down before they go at it. Maybe 15 minutes for the first one. They have the tools. Did mine that way.
Just make sure they are the right Bosch made sensors with pigtails crimped to the sensors.
