21390, would non-shimmed cams give me a "21" CEL? Posted by tim97rs, Apr-25-02 11:56 AM if you know my current issue, i have the mild regrind cams that need to be shimmed. i drove approx. 2miles with them in and unshimmed and i have a 21 CEL and a rough idle. could this be from the non-shimmed cams? (shims come in tomorrow) | |

21391, RE: would non-shimmed cams give me a "21" CEL? Posted by eclipse804, Apr-25-02 01:10 PM 21 is for the o2 sensor, but I guess the rough idle might cause very strange air/fuel readings and cause that code. Or else maybe your o2 sensor just happened to die (they only last about 2 years typically). | |
