So the CE light came on a while back, Low voltage Bank 1 and 2 Sensor 2, and the MAF (can't remember the codes exactly, they're on the service bill if it makes a difference)

So We replace both O2 sensors, and have the engine tested, and find that there are vacuum leaks at the intake gasket and the injector o-rings. So I have the dealer replace all of it. CE is off.


50 miles later, driving through town, it pops back up. I haven't had the codes read, but I'm assuming is the same one. Now I noticed that the dealer never reset my computer after they replaced the gasket, so its sitting right now with the battery disconnected and we'll see if that makes a difference.

Dealer also said that the exhaust system checks out ok. What else could be causing these codes to pop up? Mileage is sucking ***. Performance isn't. A little low of an idle is about it.

(On a side note, the dealer also changed my oil without asking me or telling me, and didn't use synthetic..grrrrrr pissed off. I guess I can't complain, I paid $50 total for all the work, including replacing the ABS electic hydraulic control module, look up the price sometime heh)
