hello, recently a new member here.. I picked up a very well maintained 1992 chevy c1500 with 305. It was a one owner truck, the only issue I have is here in TN I have to pass emissions. Basically for this year just a visual (catalytic convert) and tail pipe test. Well the owner told me, just unplug this wire(tan/black) because with it connected it won't pass. Seems to run rich.. ok, I disconnect and it passes.. then I wondered.. what's that wire. Well I found out it's the timing bypass.. now I've gotta figure out why that's being done.. so I had it scanned and got a code 42.. is it simply the ignition control module in the distributor? Can I be that lucky?? Any help would be great. Thanks Jason
