I just had a Motorvations stepper pulley installed for the jrsc on my 98 ITR. About a day later I got a CEL. Before I could get the car in to have it checked out the CEL went away. Anyone have any idea what could have caused this? I didn't notice any difference in the way the car ran, but I didn't push it too hard while the CEL was on. Thanks for any input.

if you test it, it will still display whatever caused it to trip...
