I have a 1996 crown vic i need to know these touble codes po305 po304


P0304 means that cylinder 4 has a misfire and P0305 is a cylinder 5 misfire. What this means is you may have bad spark plugs, or bad plug wires, or you may need to replace your distributor cap and rotor. I would start with plugs and wires.

Code p0300 coming up random cylinder misfire already changed wires had cylinder 5 misfire .should i replace coil


If you already replaced the wires, I would suggest replacing the plugs, distributor cap and rotor. They are also very important parts of the spark. Fuel injector problems can also cause misfires.

1999 safari van 4.3 6 cyl. has a service code PO


P0301 is a DTC code that indicates a misfire to cylinder one. It could be a bad spark plug, spark plug wire, rotor and cap, a dirty fuel injector, or the worst a bad head gasket. Cylinder 1 is the first cylinder on the drivers side, towards the front. Start with the simple and check the spark plug wire and add fuel injector cleaner to the gas tank. Good luck and hope this helps you get you van running 100% soon. If that did not help, then your going to have to do a tune up by replacing the spark plugs, wires and rotor and cap. You can get all the parts you need at Auto Zone and they can give you the step by step to get the job done with common tools in under 2 hours of your time. Keep me posted, be glad to know you got your van running 100% again soon.

What do these trouble codes mean po306 cyclinder misfire detected .how do i fix the problem?


it means you have a misfire on the number 6 cylinder

this could be caused by a whole lot of reasons.

start by inspecting for a bad plug wire if it has them

check for fire on the cylinder with a spark test tool from local part store

if it is a coil-on-plug set-up, check the coil for fire

replace coil/plug wire as needed, replace boot on coil if coil needed, replace spark plugs

Check the plug wires with a spark tester, to see if they all spark good. That will verify all of the parts you replaced. If they look good, do a compression test on cylinder five.

You either have a bad spark plug wire or coil pack. The light gray color on plug is normal.

99 5.2 durango :pulled codes for multipe missfire cylinder #5-7


Aloha We have just replaced all of what you have replaced, plus water pump, fuel pump, pcv valve and 02 sensor. Took it to mechanic today we had misfire on 1,2,6,7. Mechanic said that the 99 dodge is known for bad computers, he checked ours and works great turns out that it was the coil. Ours was jumping 1/4 inch and had a orange/yellow spark. it is supposed to have a 1 inch spark and be blue. This has solved our problems after 527 dollars later.
Check the coil!
