I have a 2001 crown vic police interceptor, when im driving the motor is acting real sluggish and when I go to accelerate from 40 to 55 it jumps real bad and on the engine code it always says cylinder 5 misfire, and I have replaced everything on 5 and 6 cylinders, what is wrong here??

take a look at the EGR valve it could be either vacum controlled or electronic either way what seems to be the problem is that the valve is stuck in the open position until the engine warms up you can gently tap the egr valve with a small hammer or a screw driver and you can see that it runs smooth, now if the egr valve is vacum controlled replace the valve. if it is electronoc controlled replace the valve and the module for the egr valve.

milage on this shouldn't matter, the light being on is probly just stuck, however you maay wanna check to be sure the brakes aint hangin up a little,

Also the surging can be causeed by the fuel pump goin out, may not be the case but something to look for, it will show up as random misfires as well, maybe try a good fuel addative, (could have a little water in it, check the fuel filter as well, alot of cars now days have a charcol filter and when they go bad they can be a issue, Pick up tube could also have a hole in it, the fuel pumpo on theese cars should be in the tank and are not fun to replace,

hope one of theese suggestions helps, there are many thing that can cause the problem your describing

Have you checked the fuel filter. Fuel pump will pressure up, but fuel filter could be clogged and not work without the pressure of the fuel pump.

The backseats of this vehicle do not fold down. They are placed on hooks and then they're bolted in on the bottom right and bottom left of the seat.

SOURCE: cylinder 4 misfire on a 2000 crown victoria interceptor

first cylinder 4 is the last on the passenger side . first pull the coil out and check if there is water where the plug is. if there is take the water out and dry up the coil. if you find water you got a crack manifold or a bad intake manifold gasket. if there is no water replace the coil. good luck
