Customer Question. Hello, I have a 2000 Ford F250 6.8 V10 with a misfire. This occurs both hot and cold, worse under load. The ignition and fuel system check out fine.There are no codes and never a check engine light.I suspect there may be a base engine concern, but I have never seen such a problem with V10's. Thanks for your help, Dave. Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. 2  They are installing a fuel filter and fuel pump at no charge to me. 3  Molly USA. 4  I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. 5  Thanks again to your service.

The check engine... show more 2006 Ford F150 4X4 5.4 3V. The problem has been on going for a couple months now. When the truck is under load (going up a hill etc..) or when I hammer down and get the RPM,s above 3000 the engine begins to miss and shake.At first I thought it may be a fuel filter issue but the problem clears.The check engine light will come on for a short time then goes away.hen the truck is under load (going up a hill etc..) or when I hammer down and get the RPM,s above 3000 the engine begins to miss and shake.

I have a '99 F350 V10 with the same issue...threw a P300, and a P0174 for a bit (lean condition bank two). I wonder if I have a band tank of gas which is causing a random lean-out misfire across the board, and got that P0174 the once due to perhaps crud or water cutting out injector(s) on bank 2.i new here and am really impressed with what I am finding here, looking forward to being a regular! I just bought a mint 1999 F250 Triton V10 (5 speed) and now less than a month after getting it I have a low speed miss I just can't seem to solve.

My F250 with V10 had the same prob. After the engine got wet it would miss. The prob was the insulating cover that covers the COP to the plug. Over time they develop cracks and when moisture gets in the plug well I would get the miss.It did not set the MIL light(check engine).y F250 with V10 had the same prob.

A misfire under load complaint can usually be broken down into 2 categories. The soft misfire, often called a surge, is commonly associated with fuel related issues. The sharp misfire, on the other hand, frequently relates to ignition problems. misfire under load complaint can usually be broken down into 2 categories.

Finally figured out my misfire problem. Ok to start, my truck is a 2007 Ford F150 5.4, the problem was that it missed under load (hard acceleration or in overdrive) the cel would flash but not stay on, so I borrowed a reader from a friend and got it to read as it was missing.k to start, my truck is a 2007 Ford F150 5.4, the problem was that it missed under load (hard acceleration or in overdrive) the cel would flash but not stay on, so I borrowed a reader from a friend and got it to read as it was missing.

There are several ways to find out if the COP ignition coil on your Ford 4.6L or 5.4L is BAD or not. One is using a spark tester and is the most accurate way of testing for a BAD Coil-on-Plug (COP) ignition coil. The other is without one and requires that you swap the some COP coils to find out.here are several ways to find out if the COP ignition coil on your Ford 4.6L or 5.4L is BAD or not.

Diagnosing Misfires. Misfire is a common drivability problem that may or may not be easy to diagnose, depending on the cause. A misfiring cylinder in a four-cylinder engine is, pardon the pun, hard to miss. The loss of 25% of the engine's power output is the equivalent of a horse trying to run on three legs.iagnosing Misfires.
