I ran KOER twice, the first time I got codes 21, 94, 44, 31. Second time i got 94, 44, 31. Should i ignore code 21 since it did not appear in the second test. The temp gauge was 1/8 way up before first test, its about 80* out, so it should of been close to operating temp.

Ignore rest of codes=smog devices deleted

 

Yep.... ignore it..... coolant temp needs to be >170°F for that code not to show during a KOER.

 

ok, thanks man...
