I have a 98 SLS and my check engine light came on, for codes P0122 and P1122. Also the RPMs kinda randomly rev.
I replaced the throttle position sensor and it was fine for a month or so, then it all came back. any ideas?
TPS learn procedure? Not that I know of, my factory service manual didn't say anything like that...
I did look for bad wiring at the sensor and at the PCM, but I didn't pull the rest of the harness apart, I kinda doubt there would be any problem inside the conduit
