2006 5.4 stalling and down on power!
I picked up a 2006 5.4 lariat from a buddy. He was told by the dealer it needed a motor due to sludge and metal shavings. He parked it and bought another car. I had it shipped to my office here and now I guess it is my problem . Anyways it has 81k on it and to tell you the truth it doesn't sound like the engine is bad. It does stall at lights sometimes and it feels like it is running on 3 cylinders. I really just drove it to and from my home about 15 miles total so far. My code reader is dead and I am waiting for the new one I ordered. I check the oil and I do not see shavings. I think the dealer may have been milking him. What should I check 1st?
There is a video of startup.

I figured someone could make something of this invoice from the ford dealer.
A C/S Check engine light is on. engine stalls when idling, just had both cam sensors replaced, check and advise 79.99 diag
12000s diagnose fuel and/or electrical and computer management systems
705 oliva, dave lic# 260000
c
81173 tech 705. . 1.0 scope engine, Cam sensor codes, perform tests, customer declines engine at this time, engine sludged and metal in oil.
He got and oil change and diagnostic fee.

is your buddy the original owner of the truck or did he buy it second hand? what is the maintenance history of the vehicle? i find it hard to believe a 2006 with low miles would be sludged up if the maintanence was done on schedule. these engines are pretty easy on oil and will not build up much if any sludge as long as you use a good quality oil and change it every 5-6k miles. the new ones even specify 7500 miles i believe.

the truck doesn't have a fram filter on it by chance does it? that bit of noise at startup sounds to me like a faulty anti-drainback valve as is common on fram filters.
the invoice you have states that there are cam sensor codes. that could definitely cause the truck to stall at lights. i would find out what those codes were. the dealer probably won't give them to you since they want you to buy an engine. go by autozone or one of the many places that do a free scan and find out the codes. politely decline the parts they try to sell you and come here to research the codes they give you. i would check into that first.
also you don't mention when the last time PM has been done on the truck. i know you said oil changes were done regularly, but how about fuel filter, air filter, spark plugs, etc. a little maintenance can go a long way to make the truck run better.
also, if the plugs have been done recently, were motorcraft plugs used? that is the only plug i would put in a ford engine as they are VERY picky for some reason.

Well I picked up a code reader this moring. The computer had 5 codes stored.
p0300 Multiple misfire
p0303 cyl. 3 misfire
p0307 cyl.7 misfire
p0345 camshaft position sensor a circuit bank 2
po 349 camshaft position sensor A circuit intermitant bank 2
I cleared these and got p0345 and p0349 back.
It has a motorcraft filter on it now. The dealer changed the oil.

I don't hear one but any idea where a common leak area would be? Can the vacuum system be presurized like you would on a turbo car?

as far as the misfire codes, they are probably a result of the rough running from the cam sensor being out of whack. i would diagnose and repair the cam sensor issue first, then worry about the misfire codes later if necessary.

It was actually $400 to replace both cam sensors. It was done about 2 months ago. He did take it back and was told something is wrong with the motor and to take it to the dealer. The dealer got the same codes and determined he needed a motor. I cannot take it back as the truck is now in Michigan and the work was done in Florida. I assumed worst case it would need a motor. I am just really questioning that. I am thinking of picking up a new cam sensor and replacing bank 2. That are only $25 on ebay for new ones. Which is bank 2 ?
