If the spark plug is firing, check that the injector is pulsing, is putting gas into the cylinder. If both are working, do an engine compression test. If that cylinder is low on compression, you have a mechanical problem-maybe a valve is not sealing, maybe a burnt valve; the cylinder head will have to be removed to find and fix the problem.
Pull the spark plug after it has been run and see if plug is wet with gas or smells like gas. That's one way to check for gas in the cylinder. Or put a "noid" light on the injector connector to see if the injector circuit for that cylinder is working. Noid lights can be bought at a parts store cheaply, just make sure it fits your connector.

    A noid light should blink when engine is running or cranking. If it does, the circuit is good.

SOURCE: replaced plugs wires coils and still eng. misfire

ok. You mentioned shampoo? meaning you cleaned the engine and compartment. And ran out of gas.
Sometimes if we wash the engine, water can hide in some spots like getting into plugs and such. If so, that plug may have been damaged. change the fuel filter as well, if you have ran out of gas.

if smell rich, well you just may be on the right track. Not enough air. Be sure to check all vacuum hose to ensure you don't have a leak somewhere that we are not catching.

SOURCE: 2002 kia sedona 3.5l has rough idle replaced plugs wires and coil

this vehicle has coil packs for the ignition correct? have you ran the engine at night with all surrounding lights outs so its really dark. spray a mist of water on the coil packs and spark plug wires to see if you have spark/voltage leaks jumping out from them. sometimes the tiny sparks will be so fine and skinny you can barely see them so it needs to be dark. hope this helps your trouble shooting. a coil pack could have such a fine crack for the voltage to leak from that you cant see it.

Po300 & Po305 on a F-150


P0305 is cylinder #5 not firing. P0300 is random misfire which the computer cannot determine which cylinder(s) are misfiring. Check to This will make a lack of response or no power when the pedal is depressed. P0300 can be caused by spark plug wires needing replacement if equipped.

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.

Engine light on / runs rough / Sometimes dies Has code p305


Code po305 is # 5 cylinder misfire. Check the spark plug wire and spark plug. use an inline spark tester to check the wire from coil to spark plug. If you have spark,then remove plug to see if it is fouled out. the best time to check for brake or cracked spark plug wiring is at night with engine running and doing a walk around to see if the insulation on wireing is broken or cracked. you will see the wires sparking at night. then replace the wires that are causing the problem.

Misfires and codes PO316, PO306, & PO305 popped up on the diagnostics check. What needs to be fixed based on that?


You will need to replace no 5 and no 6 coil pack and spark plugs. P0316 is random missfire that computer could not detect the cylinder that was causing it,just knew one was missfiring.
Coil packs are common concern on these vehicles. Can get oil leak into the coil pack wells and may also even get moisture into them.
If yours is a 3.9L it may be involved in owner satisfaction program 07M07 or 07N09 in which they will cover them under the program for up to 10yrs or 100000 miles which ever comes first.

Cylinder number 5 is misfiring. Check spark plug, spark plug wire and ignition coil for the number 5 cylinder. The number 5 cylinder is the closest to the front of the car on the drivers side. With engine running in dark (at night) take a spray bottle of water and lightly mist spark plug wires and coil and look for arcing. Autozone will test coil for free.
