On 1995 Crown Victoria the EGR valve is located at the rear of the engine compartment. While the attaching bolts can be gotten out with a little bit of a problem the egr tube that atteches the EGR valve to the right exhaust manifold is a pain. It is possible to do though. Here are the removal and installation instructions. If you are sure that the EGR valve is the reason for any check engine light then you can remove the battery cable for about five minutes to reset the light, but if the light is on for a differant reason then you just got rid of the code plus any freeze frame data that a shop could have used to diagnose the problem.

My 1996 Crown Vic. recently started to buck and backfire a bit, turned out to be a misfire on #4, have been looking into it with a bit of progress but not complete success
I have faced the same thing with my car, this is not a single answer to this problem. It could be a bad boot on the coil pack, it could be a improper coil install, sometimes the spring does not sit in well, it could be that the intake manifold is leaking, it could be that the egr valve is stuck, it could the exhaust manifold is leaking, sometimes these issues are not caught by the OBD 2 sensors, you can try to move the coils around to see if that works out.

How to replace the egr valve position sensor on a 1994 ford crown vic
the positions of the EGR are close, but they are 2 different units. Look on the back of the upper plenum. You will either see a round aluminum item with an orange/red plunger in it that bolts to the 90 degree elbow, or you will see a plate that bolts to the upper plenum itself. The round aluminum one is the EGR Valve for that model. If it has the plate bolted directly to the plenum, that will be the backpressure transducer.

On both models, you will see a round black plastic cylinder unit. That is the EGR solenoid. There will be 2 tubes on it - one to the upper plenum and fuel regulator, and the other to either the EGR Valve or the backpressure transducer.

Either one you have, they are hard to see. They are on the back, and hard to work on. Mine had the EGR Valve on the elbow, and it was tight to get on/off. I found the easiest way to get it taken apart is to take the elbow off, then the EGR valve, and work on it this way. Made things ALOT easier. Just be careful and try not to break the gasket in between the elbow and the upper plenum.

My egr vaulv i dnt knw how to change it on my crown vic
It unbolts from the throttle body and the pipe is screwed into it. But are you sure you need one. They rarely go bad. Usually if you have a check engine light on for the egr valve it is because of a bad DPFE sensor or a plugged passage in the throttle body.

Ford Crown Vic p0300 random cylinder misfire
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.
