Hello, I am a new Ford ranger owner I am 18 and I have had the ranger for 2 weeks now. (2004 Ford ranger 3.0L V6) I Recently had a misfire in cylinder 6. The spark plug smelled of fuel and was really wet. I replaced all 6 spark plugs to brand new ones. A few days passed with the engine running smoothly, but now its back, but the spark plug does not have an issue with it. I've checked the cables and they do not seem damaged. I wanted to know what could be the most common issue.
I would also like to know the best Ignition coil pack for the ranger.
Thank you!

Info:
215 000 Km on it.
Misfire came back after oil change (if it has any relation)

 

Switch a plug from number 6 with the misfire with another cylinder.
If the misfire moves from 6 to that cylinder, then the plug is faulty.

Logically most would change the coil pack and wires, but do a compression test first.
Should be at 160 to 165, anything below 150 is not with in spec.
With out checking, your 2004 may fall into the "soft valve seat" category, so a compression test needs doing to rule that out.

Do one plug at a time with all the plugs removed.
Hold the accelerator pedal all the way to the floor so the engine won't start and turn over at least 5 to 6 revolutions.

Be sure and get a compression tester that fits down into the spark plug hole properly, use the "threaded" type.

As Jeff said, do a compression test as soon as possible to take valve seat issue off the table..........or to find out it IS the problem, otherwise you will just be wasting time and money on non-fixes

 

Update: It only misfires when my tank gets low on fuel under a quarter tank. when it is above quarter tank it runs fine.
