Not really fixing, just replacing. For my 86 El Camino, it has an OBD1 diagnostic port. Back when I converted it to a throttle body fuel injection, 25+ years ago or so, there were no kits like are on the market today. I cobbled together the parts from a GM 1990 Pickup truck Vin H model and adapted it to my Elky. I had to have a custom chip made for the sensors and the 200 4R transmission to put the transmission into full lockup at 50 MPH.
Anyway, the tool I used to read codes is an Auto X-Ray unit. It worked for many years, and recently I had a CEL light come on, and then go back off. I was curious as to what the code was. My old Auto-X-Ray would not come on, just one beep, and no display. I can short out two pins and get the CEL to blink the code, but that is a pain, and I wanted my tool to work. I found one on EBAY, used of course, and it works perfect. $48 bucks, and it has a case, and several cables even a OBD2 cable. No codes to read after all this time to get the new unit in.
Then I had to make a place to hang the new unit and the case it goes in.
