Just bought a 2004 F-150 4.6 New Style for $3,500 last week, scanned it before buying it and codes were p0171, p0301, p0351 figured it just needed plugs and new cop's so I went ahead a paid for it brought it home and I noticed it only would miss when coming from a stop

Replaced the plugs and cop's and erased the codes, it was running good then about 10 minutes later check engine came back on scanned and got the p0351 again and also got p0506

Next day truck wouldn't start ended up replacing the fpdm and it starts up now, but I can't figure out why I'm getting the p0351 I've already inspected the wires running to the cop and everything looks normal

Also if I clear the codes the truck runs great until the engine light comes back on, so when that happens I just pull over clear the code and it runs good for another 10-20 minutes
