2011 5.4 3 valve POS.
Sometimes stalls at idle. Tap the throttle and it's OK. Othertimes it's OK. No problem with mileage. No problems at speed. Oil level OK.
History. Recent replaced, chains, guides, phasers, Cams, followers.
2 days ago, driving an incline at 80 mph a heavy clunk. Not so loud but like I had hit a deer dead center. No problems the rest of that day.
Yesterday, started rough idling, stalled 2 times. Today, intermittent rough idle. Driving 300 miles to home.
Initially I was thinking it jumped a tooth. But would it be intermittent? Then because a tap on the pedal straightens it out, oil pump going out?
