Doing it again. About 24 hours it was fine. Now, at start-up when it's cold, it's fine. I drove about 10 miles, parked for about 20 minutes, start up and there's that goddamn light. Have to restart twice to get light out. Go home, shut off, restart, light's on. And the tapping in the top end. A-goddamn-gain. I rev it a little and the light goes out and tapping quiets until the revs fall back to idle. Then it taps and the MF'ing light is back on. I want either this car gone or this problem gone. I'm looking at another car tomorrow so hopefully the former. Any ideas on what this could be? Failing oil pump?:sad:
Edit: there's less than 70k miles on it. No car should have these problems with less than 70k on it.
