1991 GT... I got a code 67 in the KOEO test, but no error codes (11) in the KOER test... can anybody translate for me? I ran the test because I began to notice that I got the Check Engine light when running over 3000 RPM while the engine was cold... once it was warm, the light stayed off. In addition, the occurs only in cold weather. I wonder if the computer is stuck in open loop? Either way, I would appreciate it if someone could help decipher tthe code 67. Thanks.
