I had a plugged cat so I got rid of it, took the air tube off and plugged the crossover tube. All I've got for an exhaust system is a o2 at the cross pipe (stock placement) and 2 cherry bombs. It ran fine and then all of a sudden it started running like it was fireing on only 4 cyls. Taking all the air pump stuff off, wpould that cause the computer to start reading strange signals and respond in like manner?
