Just wondering if an exhaust leak can cause false kr or real kr for that matter. I have an exhaust leak near the collector and hope to alleviate it with a new downpipe. Anyone have kr with exhaust leaks?
could be wrong but, it could cause kr, because air is escaping. Close by the rear collector, is the o2. your car is programmed to dump fuel for how much air is going through, but since you are losing some air, it could throw off your o2's. i don't know, i could be wrong though.
