Gutting the cat. Big mistake. The O2 sensors are now sending the wrong information to the engine computer.

I installed the spark plug foulers so it's not growing a light for the o2 but ran fine for a few hours after I did that and then all the sudden it started missing I got the control module off gonna get it tested tom but u think that I need to put a car back on it cause it's causing the miss i have done this before to the same motor in dirffwrent truck with no problems
