Hey everyone. I posted a couple weeks ago that I had a P0301 Diagnostic Code and I was able to fix that problem. However, today my check engine light came on and now I have a P0300 code. I went to a couple Auto Mechanics and they’re trying to charge me an arm and a leg for repairs. Im a quick learner and a bit car savvy and was wondering if anyone had recommendations for repair procedures. I want to spend as little as possible if I can. All help is welcome.
