I just installed an off road x pipe on my 97 cobra. Installed the mil eliminators. My check engine light popped on and I got codes p0155 and p0430. Are my eliminators not working?
P0155 suggests a problem with the front sensor on the driver's side.
P0430 is a catalyst problem in the driver's side.
So the 0430 is saying something about your MIL on that side but the fact that a 0155 also showed up on the same bank suggests something else might be up with the wiring or install in general.
