Ok where to start? Im wondering if I have a bad PCM. I was chasing a EEV IV code 31 KOEO. I used this link EGR/EVP Codes 31/32/33/34/35 Troubleshooting - SBFTECH.com to go by. I did all the tests and the results point to a bad PCM. Also performed a KOER test and my Bronco started smoking like all hell and hasnt stopped since. And before the test it idled fine with a hint of richness. So now Im at a loss as to why she started during the test and hasnt stopped. Does this seem to point out bad PCM? Also have a code 18 in memory that is always there even if I clear it. Timing advances like it is suppose to and idles smooth. Still have the code even with a new ignition control module. Any help would be greatly appreciated. Im ready to drive this truck of a cliff with me in it. Thanks again
