OK...got a 84 B2 2.8...wasnt running right black smoke and junk coming out the tail pipe...posted earlier, was told to pull codes to get a better idea what is wrong. The codes I got were 13,21,23,24,31,32,33,34,41,77....seems like alot..thought tht would get like one or two...checked this 3 times and got all the same codes each time...not real sure what any of it means found some of the codes meanings but wasnt much help. Anyone that has any idea what all these codes mean in common man term, could you please let me know. Thanks ahead of time for any help!!!!!
You need to tell us if they are KOEO, KOER or continuous codes, see the link in the tech info post on pulling the eec-iv codes. It looks like you have something going on with the IAC, EGR, O2 and you didn't goose it when prompted.
althought looking agian at instructions I did use KOER and used the test light on pin #4 on signal return...but I also ran a jump wire from the sig rtn to the selt test input...is that incorrect??
