I need some help here guys. The car got a cel p0121. Checked the resistance like bentley says and it was a little off. I replaced the TPS but when I check the voltage on the harness I get 5V on pin 2 not on pin 1. Car is still stumble when I hit the gas. Could it be the ecm that is having problems?
