Guys with car knowledge I need you. I have an odb2 can shield that I can write pids to and I'm looking for a p0301 and p0303 error codes because my ignition coil failed. So I'm just wondering if I clear the dtc if any issues that are present would show/trigger again?

    No lol. It's a shit bucket. It just stresses me out that it has the MIL on.

    From my limited understanding, if you clear the codes without fixing the problem, then it'll come back sooner or later. (When the car detects it again, when you scan for codes, etc)

    If the underlying issue persists, the light will come back on at some point.

    Sometimes when I have got an error for a fuel lean or rich condition, it won't come back. It has been likely due to bad fuel or something
