I took the spark plug wires out of my 1999 Mercury Villager-

easiest way to test the coil is to put a hose about 3-4 inches long on coil then put spark plug in other side of the hose and have a helper turn the key. look for a blue spark at the plug. if no spark then that side of the coil is bad.

P0301 - OBD-II Trouble Code - RepairPal

I had that happening too, the diagnostic was random misfire. I didn't know what cylinder so the distributor cap, the rotor and spark plugs wires were changed it helped. The light still comes on now and again.

have you checked the fuel pressure regulator

I think you should take it to a repair shop, to have it
properly diagnosed & repaired

Your asking what someone thinks--how would we do that?

Your then asking, if you should try something else,AFTER
you were told what the code was,(a misfire on cylinder #5)

Now you see why I don't think it is within your ability to resolve?

You didn't post your engine size so please pick the applicable motor:






Firing order and spark plug wire installation for the 2.5L engine





Firing order and spark plug wire installation for the 2.0L engine

pull the leads one at a time from the coil pack. if you pull a spark plug wire and the engine rpm doesn't change and there is a weak or no spark the coil pack is likely the problem.

if you can get a plug socket on the sparkplug proceed as usual.

Here is a image of it's location, I hope it helps.

check the spark plug wires, put water in a spray bottle and spray along the wires,especially by the coil,if the car starts to run bad or you see sparks, the wires are no good, hope this helps, Ray
