Car vibrates at idle since I bought it January 2020, Past few days rpm's dip at idle, twice now to 300 quickly recovers, intermittent droning like a mis and a lack of power. Both fuel pumps look a little weak but wtf would cause this. All other maintenance is up to date Index 12's very quick starts but sometimes you can hear a mis on cold start. shadow code 2aaf recently and lpfp sensor was dead for a few months. replaced then seems like things got worse. I'm willing to bet it's a leaking injector but It's not wetting plugs. what a fucking pain
