Question about 2008 Ford F-150 SuperCrew

2008 Ford f150 misfiring and flooding itself out. What is wrong?

The engine started misfiring and flooding itself out. I've replaced both cam sensors, spark plugs, coils and boot. It still misfires and floods itself out. It barely idles and fills the cab with fumes.

The engine is getting extra fuel from a ruptured fuel pressure regulator it is located on the fuel rail and gets manifold vacuum to operate remove small hose and if has gas in it the replace it.

Testimonial: "After alot of "process of elimination" - we pulled the valve covers and found a bad cam follower, bent valve and lifter in pieces on the #4 cylinder."

    Wow that was a lot of stuff bad it seems the the cranking speed would have been uneven with this type of damage. Look at the valve carefully for galling (transfer of metal) it may have ruined the guide also.

How to start floded engine 1998 ford f150 truck 4.2 engine

The (TPS) throttle position sensor realizes there is a flooded condition when the operator presses the pedal to the (WOT) wide open throttle position. However, the usual cause is a bad TPS. Replace the TPS, not a difficult job two screws and an electrical plug.

I have a 2004 f150 that won't start but can hear the fuel pump cut on

run fault codes to determine the sensor that is faulty. Check for cam/crank position sensor. Check that the cam shaft is turning(broken timing belt/chain). Check that the immobiliser is operational.

2007 Ford F-250, 5.4 Engine-Missing, running very rough at idle-very low idle. Engine codes P0011, P0022, P0171, P0300, P0305, P0307, P0316, P2198.

Hello, There is an extended Warranty for "Cam Phasers". I want to say 7 Years and 90,000 Miles. But some of the repairs are on a case by case basis. Years 2004-2008 were affected.

I will tell you what your Codes mean.p0011 and p0022 are both for the Camshaft position sensors. One side is overadvanced and the other is retarded. Code p 0171 is an O2 sensor, Code 0300 is random misfiring, Codes p0305 and 0307 are the #5 and #7 cylinder misfires. Code p0316 is a general misfire when starting up, and finally the p2198 is a rich condition O2 sensor on bank2 sensor 1.

All of these make sense when the Cam on bank 1 is over advanced you will run lean and the Cam on bank 2 is retarded, you will run rich. The misfires are from incorrect timing and affected fuel mix.

There are "cheater tools" for this repair which will cut Labor costs in half. Check the Web for Mac tools, Snap-on, and so forth. The cheater works by pressing down on the internal chain tensioner to make slack in the timing chain. You take off the valve covers and unbolt the Cam (Phaser) gear and sneak it out through the valve cover opening. The CAM PHASERS cost $300 to $500 apiece.

A normal repair without the cheater involves removing the front of the motor up to the heads and still requires removing the valve covers.

I hope my solution is very helpful to you, at least you know why you are getting the Codes you are reading.

the cam sensor will keep the vehicle from starting, so if its starting then I doubt its a sensor problem unless there is a pinch in the wire, grounding out somewhere. but this will kill the engine as soon as it happens. and also a bad o2 sensor will only make the engine use more fuel, and kick on the service light... does it have a ticking noise, some of the early 5.4 in the f150 had a TSB for the cam phasers, which gave a p code for the cam sensor, and for some reason spit one for the bank 1 sensor as well. this is an ongoing problem with these 3 valve OHC 5.4 engines, I would suggest taking it to the dealer. im sorry I could not be of more help, but like I said this is an ongoing problkem I still have been tinkering with.

2004 F150 5.4L engine misfire

The concern is likely caused by the coil which sits on top of the spark plug. Your P0301 indicated misfire on cylinder 1. Your P0316 indicated it occurs on the first 1000 revolutions. Your P0171 indicated lean on bank one. Bank one includes cylinders 1,2,3 and 4. Your lean code is strange but could be related to misfire. I would recommend swap the coil on number one with number two. Clear the code and drive it. I would expect to see a P0302 which indicates the misfire traveled with bad coil. good luck.
