No, but with the stock program in, it will accasionally set code P0430. Could that be affecting the other codes while the speedo program is in?
Basically this means that the oxygen sensor
downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.
A code P0430 may mean that one or more of the following has happened:
* The catalytic converter is no longer functioning properly
* An oxygen sensor is not reading (functioning) properly
* There is an exhaust leak
this has nothing to do with our product being installed.
