Kinda seems like I'm talking to myself or blogging or something, but just throwing out as I see it. I cleared the P0300 code and came back again. So I'm thinking the only way to get rid of it is a tune. That might take a while to get together. I did have my AFR checked during idle. When it dropped below 900 rpm, it went to 13.5, and when it revved up between 900-1200, it goes to 18 and sits there till the next stutter back down to under 900 rpm. From what my mechanic is telling me, a good AFR at idle should be 14.5, anyone know more about this?
