So 4 months in to owning this 99 suburban Im dealing with a missing cat on the driver side down pipe and the 2nd original cat is still on the passenger side down pipe . So someone I know mentioned and noticed all this when I purchased the truck “ said it could lead to engine issues down the line sooner or later …. I just wanted to know if this scenario is actually causing my engine to run maybe richer or leaner or hotter off one of the two sides of the engine bank ?
I don’t know how long the truck had the one cat missing maybe years now …but now 4 months in driving a p0430 code arrived.
It says online a p0430 really would never be a cylinder 1 “drive side” issue and that it is a bad Catalytic converter or o2 sensor issue off the passenger side bank of the engine
Below is a CA emissions exhaust setup for a 99 gmt 400 suburban
My Driver side cat is gone and filled with a 12” flex pipe
Any suggestions if I still have time to add a cat and should they both match in a sense? Should I do both new in a specific type maybe high flow or both just to make them alike , I’m not sure if an oem stock operates differently then a cheap aftermarket ?
Will doing this fix all this time later spare any type of catastrophic failures
Surprisingly the engine runs smooth and sound in every way aside from the missing cat and the sel code
