Chronic Boredom
Hey everyone, to start with I have a 1993 Chevy C1500 5.7L. I did the paper clip trick and found I have Code 44 for lean exhaust. The check engine light is never on at startup, it will turn on after around ten minutes of driving every time. Thing is, it's been running fine so I don't see why it would be lighting up. So far I've changed the oxygen sensor, got new spark plugs and wires, fuel filter, and air filter. As recent as a few months ago, the ignition module, rotor, and a new delphi fuel pump was replaced after it left me stranded. It's been running like normal ever since, except for the light that started turning on a couple weeks ago. Any ideas what it could be? I don't have an exhaust leak as far as I can tell. It's starting to drive me crazy. Thanks.
