I am having some occasional idle hunting issues with my 93GT. Pulled codes KOEO-67, this appears to be clutch/ neutral switch related. I have since read that with a KOEO code 67 the KOER test will not work. When I pulled codes, I ran both tests and the KOER test did work, I could hear it cycling and I recieved a code of 11, which indicates everything normal. Could a code 67 cause hunting idle issues? I remember when I did run the KOER test the book had me push the clutch, I think 2-3 times.

If you run the KOEO self test with the transmission in gear, code 67 will show. Place it in neutral and rerun the KOEO. If you have to keep the clutch pedal down to allow the KOER to be run, there is a problem. LUK
