After allowing my 84 2m4 to idle for a minute, I recieved a trouble code of 45 (Rich Exhaust). I replaced my oxygen sensor and check all hoses... I removed the neg. battery cable to reset the ECM. After allowing to idle again, I got the code 45 again. What's next? Thanks, for any help.

How cold out is it? If it's below 40F then check the Thermac. If the thermac doesn't work then the IAC passage can ice and cause a rich mix. (My 87 does this all the time. 87 deleted the thermac. It's annoying as hell.)
