Question about 1986 Chevrolet S-10 Blazer
2.8L V6 4x4 auto trans. only code 12 shows up. have had past vacume leaks (rotton lines)

I would start by changing the fuel filter. Run some injector cleaner through it. And check for more of those rotten lines. You can check by spraying a little starting fluid around the vacuum lines. Be careful though. Its flammable. But the engine should speed up if you have a leak.
