Re: Codes
I think 22 is the TPS sensor out of adjustment, and code 42 is the timing. That one will set if you disconnect the black/tan connector to set the timing. You can ignore it if you have set the timing recently.

Re: Codes
There is a tech article on this site on adjusting the TPS and IAC sensors.
