Is this true??? Lets say your cat is no longer there and when you reset your ecu the check engine comes on but after a few days the light goes off is this common? When the light is off does the timing go back to normal?

the ecu has stored the prob. when the lite goes out,if it is not a prob.... just a change its not use to.

The problem will always come back until it is solved/erased for the computers memory

But will the timing go back to normal?
