Voltage Codes
In doing a OBD1 test two codes came up 121 & 122. 121 closed throttle voltage higher or lower, 122 throttle position sensor below minimum voltage. Engine light on, TPS was just replaced and up came these codes. After TPS replaced engine RPM would not go below 1100rpm, and engine hesitated when quick increase of throttle. I have a bad feeling new TPS is bad as engine was not performing in this situation.
