Ok your product makes it put a misfire code and that in turns makes it turn on the CEL. You say ignore it okay I get that.

But what happens when you truly have a CEL that needs attention that can actually harm your engine? Since the CEL is already on and the driver is used to it being on. New codes show up but the driver never knows..... until he is picking up his internal parts off the road.
