if it is indeed a clogged cat and costs $200 to fix, I'd be happy, b/c the savings on gas would cover it eventually.

 

How exactly does the cat gets clogged with less than 91 octane?? isnt it unleaded??


and How do you clean the Cats? Quemicals?? I am thinking its time to replace my O2's. I will do quemicals before the swap.

well also if im thinking right if ur O2 isnt working properly for too long this will be sending lots of unburn emissions to the cat and could clog it... but when octane is lower it just means the gas is not as clean burning, and it will give off higher emissions on a high compression engine
