Thread: Bank 1 Sensor 2 (Where and How?)

Title explains it. lol. Is it pretty easy to change and where?! My gas is crap and threw the code

that should be the post cat o2 in the U bend. and it dont do much in cars older then 01,,not knowing what year car you have.

I might as well delete it. I have a 98 GP with a bonneville 3800 swap

Gas caps don't throw O2 codes,
The bonneville engine means very little in your GP. Same engine all day long.
