Fouled plugs... :( and lots of other problems
ok i've got an 04 1500 5.3 v8. heres whats wrong.. rough idle, buzzing noise comin from exauhst at 2000rpm(65mph) only when i'm on the gas. poor gas milage. my ces readings are as follows. 1)random misfire 2) 02 sensor bank 2. 3) cat running inneficiently bank 2. 4) 02 sensor-system running too lean, bank 2.
I changed out my plugs and wire 3 weeks ago thinking it would fix the idle, it helped but didnt fix, now the 4 plugs on the left side of my engine when looking at the engine are all fouled already.
Is my cat bad? causing the 02 to read bad, causing my engine to foul out those plugs? i'm helpless here people!
Any ideas?!?!
Thanks!!!!!!!!!!!!!!!!!

thats a nightmare that is intersting.
06 chevy why would the cat cause that, by causing the 02 to call for to much fuel? but why just one side of the engine?
maybe itcould be the 02on that side of the engine before the cat sending to much fuel to those injectors

ya it is a nightmare. i'm frustrated! but the code from the ses light said it was #2 o2 sensor on bank two. my cat is making a buzzing noise as if a baffold broke lose inside of it and is buzzing from the exhaust.. so i'm pretty sure my cat is bad..

Thats to many problems to figure out without having it tested. Spend the 95 bucks and find out whats up before you go nuts.
