Code 17 help
Hey guys i have a 89 GXL and when im cruising on the highway at a steady speed the check engine light comes on and if i change the throttle input (get off and back on it the code goes away. I pulled the code and it shows code 17 feedback system Sensor output not changed after 25 sec. (FD) or 10 Sec. (FC) In feedback zone what sensor is this specifically talking about? at cruising i would imagine most sensors read in a generally the same.
