Code p0300 2001 z28 So I bought this z28 not long ago. It did have the service engine light on. I decided today to hook up the hypertech and read the code. Popped up as p0300. I deleted it, then it came back on later after about 30 mins into my drive. Funny thing is I have no violent shaking at higher speeds, no spuddering or loss of power, no strong unburnt fuel smell, ect. The car runs great, so I am alittle stumped as to what it could be. Any ideas? Completely stock beside a flowmaster. The egr is still intact.
