I have a 2003 f-150 supercrew that I purchased september 2, 2003. In october 2003 when the odometer was changing from 999 miles the vehicle seemed to have an electrical short and the dash lights flashed for a couple seconds. Then the odometer changed to 2000 miles skipping the 1000 mile mark and began to miss as if it was going to stop running but it never stopped. The check engine light never came on and the vehicle continues to misfire. I have had the vehicle checked by the ford dealership where I purchased it on six visits. They have found cylinder 1, 2, and 3 misfires and replaced the boots and coils to those cylinders. But it still misses when I come to a stop with the engine in drive or at idle and the check engine light has never come on. The serviceman at the dealership and I when on a test drive with a monitor checking the firing of the spark plugs and the cylinders were showing as much as a 60 % voltage drop.the computer has showed several codes on the cylinders and codes that are not suppose to be even on this vehicle. This truck has been serviced by dealer six times, but they have been unable to diagnose or correct the problem.

I am very dissatisfied with my 44k truck
