Check engine came on (02 Grand prix 3.8L), Cleared code P0442 (Small EVAP Leak), Check engine came back on and noticed gas cap gasket was cracked, Replaced w/new and cleared code again.. Ran very good for roughly 70 miles after topping off the tank but did notice the needle took awhile to drop from the (F) mark, I then had lose of power with no additional codes returning and now it is very difficult to go over 30MPH without having serious hesitation. Changed purge valve, fuel filter and check vacuum lines for the obvious....All looked good from what was visible... Hooked up the OBDII with laptop and noticed the 2nd bank O2 Sensor was showing voltage but showed N/A for the fuel trim as O2 bank 1 show voltage as well as a percentage reading for fuel trim... Any Thoughts?

My 2002 grand prix has a a fuel gauge with a mind of its own. I have been told that it is the fuel sensor. I need to know how to access it and the proper way to remove it and install the new sensor. Thanks in advance

back power window went down and now won't go back up. The rest of the windows work fine.

I have a problem with the mass air flow sensor where i had to clean it, the car ran fine afterward but soon returned to how it was before, it takes a little bit to get over 30mpg and it's hard getting up steep hills, then one day the hood started smoking and made a loud hissing noise, come to find out it was the secondary air valve and the cap on top had melted and the disk inside distorted, needless to say it had to be replaced, could a faulty air sensor have caused this?
