Just wondering what you think? I had 2 codes p0300 which is misfire detection and a p0172 system too rich bank 1. Test drove vehicle while watching the misfire graph and cyl 1 and cyl 2 had several hits so I changed the plugs. After thst vehicle runs good but has no power up hills the check engine flashes but dont store any codes or sets any history codes. Any suggestions.
