Hello everyone and a happy new year, especially to Thermo how has assisted me over the past years. Am experiencing misfire everymorning when i start my vehichle. sometimes the check light tends to blink. After a while the misfire tends to go away and the check lights remain steady. Additionally the brakes also tends to feel extremely hard when pressed and doesn't brake/stop properly. But that too eventually goes away. I have read my codes and it tells me its missing on all cylinders.
Can this problem be as a result of the coil packs need changing? Also the mileage is about 170000. The codes that i pulled from the car are listed below:

P0300 random misfire
p0301 cylinder 1 misfire
p0303 cylinder 3 misfire
p0304 cylinder 4 misfire
p0305 cylinder 5 misfire
p0306 cylinder 6 misfire
p1313 misfire rate catalyst damage fault - bank one
p1316 misfire rate exceeds emissions
p0420 catalyst system efficiency below threshold (bannk 1)
p0430 catalyst system efficiency belw threshold (bank 2)

But i noticed it doesn't say misfire on cyclinder 2.

Does this means i have to change my ignition coils? Any help would be greatly appreciated.

Also is there a crosss reference for the coil pack aftermarket or through ford? Am in the Bahamas, so the Florida, USA market would be most ideal for me. thanks.

satwarez, stop by your local autoparts store and see if you can rent a fuel pressure gauge. Now, with the engine off, remove the cover from the top of the engine and look for a "tire valve stem" piece that is attached to the fuel rail of your car. Connect the fuel pressure gauge to this valve stem. Make sure not to attempt to connect it to the silver lines off of the motor (shouldn't fit anyways) as those lines are for your A/C system. Now, turn the key to the RUN position, but do not start the car. You should see the pressure gauge go up to about 50 PSI (50-60 psi is good). Now, start the car and the gauge should drop to the 40 psi mark. If you are down around 30 psi or possibly even lower, then your fuel pump is starting to go and that is causing your misfires and all the other codes.

Once you get this check done, turn off the engine and remove the fuel pressure gauge. I bet you will find that the pressures are low and that is causing what you are seeing.

 

ok thanks thermo i will attempt that today and let you know.
