Ford Crown Vic p0300 random cylinder misfire

I have a 2000 Ford Crown Vic interceptor with 185,000 miles. The car only misfires when the temp is below 50 degrees it stumbles really badly. I have changed the temp sensor, plug boots for the individual coil packs, I have also replaced the PCV and the hose that runs from PCV to throttle body. Once the car warms up it smooths out and runs fine NO MISS once warmed up. The car is in top condition for the mileage other than the miss. Please any solutions would be appreciated.

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.

My 2002 crown vic is misfiring and the check engine light flashes when speeds of over twenty miles of hour are reached. Is it safe to drive. How can I fix this


you can drive it but it will damage your catalyst system, that is why the klight flashes to let you know other problems can develop. the car being a 2002 it has a misfire monitor in the computer. go to a local parts house and have them scan for misfire codes to see which cylinder is misfiring. make sure you check the intake at the #5 cylinder (which is the first one on the left side of the engine)to see if it is getting coolant in it from the intake leaking at the thermostat housing.

I wouldn't worry about the 02 code it will clear when you replace the coils. to be positive that the coils are bad, swap them with another cylinder and see if that cylinder misfires. 90% of the time it's the coil. Let me know

P0300 Random Misfire

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.

A Random Misfire code usually indicates a vacuum leak or bad gas.

NOTE: If a misfire in a specific cylinder should lead you to check the spark plug, fuel injector and compression.

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

Hesitation and stumbling.


Before you do that, check which thermostat it has in it, if it has one that is letting it get too warm or not completely up to temp when the computer think it should be, it would cause this. My 2000 crown vic did the same thing and thats what it was.

2003 Crown Vic Misfiring after acceleration


I just came up with that exact issue in my 2003 with 98K police crown vic. And the last time I had this issue in a 2001 police Crown vic it was the crank shaft position sensor. A $20 part and about 30 mins to put it in. located near the bottom of the engine. I had to un bolt the A/C compressor and push it out of the way a few inches to get to the sensor. If you have about 100K mile on it and its an idled heavy police car, this sensor should be changed out anyway. It can leave you on the road dead and some dealers have a hard time find out whats wrong as the OBD 2 does not see it as a problem when it goes bad or becomes touchy as I think mine is.
