Oil in where the spark plugs go on a 1998 mercury mystique. is this normal ?

Need spark plug wire diagram for 98 mercury mystique 2 5

Firing order of 1998 mercury mystique

Cylinder 2 is misfiring. Spark plug could be faulty or spark plug wire could have broke internally if you didn't replace them at the same time. Swap cylinder 1 and 2s spark plugs clear code and drive again. If Same code comes back plug is good look at wire if code p0301 come up the spark plug is no good

check for fuel rail check for spark you can hear the pump run when key is turned if know sound is heard check fuse,relay,pump. get spark roll over check for spark if no spark pull out mod take to autozone to have tested if good replace crank sensor

Actually they are rather simple just need extension and spark plug socket..... and in my case 3 guys looking stupid lol on n a small socket to remove cover

If the oil only covered the "outside" of the spark plug, it is likely the valve cover seals to which will be carried by most autoparts stores. Replace by using a black silicone to hold the seal in the cover(just a couple of dots here and there to hold it in will do) and this should cure the issue for at least another 60,000 miles. If you need instructons, please feel free to let me know.

ignition timing or valve timing?

ignition timing not setable.

info:
The ignition system consists of an ignition coil, spark plug wires and spark plugs.
The crankshaft position sensor signal is the basis for ignition timing calculations. The alternating voltage signal from the crankshaft position sensor is digitized by the powertrain control module. This digitized signal is then used to position the closing time of the primary circuit of the ignition coil.
Ignition angle is determined by the powertrain control module in response to engine operating conditions. Once ignition angle has been determined, the powertrain control module interrupts the current to the primary circuit of the ignition coil thus triggering the ignition spark which is supplied to the cylinders through the spark plug wires and spark plugs.
The ignition coils are triggered by the powertrain control module in pairs (cylinders 1 and 4 and cylinders 3 and 2) sending one ignition spark to the firing cylinder and one ignition spark to the corresponding cylinder on the exhaust stroke. This make sures that any unburnt fuel residues remaining in the cylinder on the exhaust stroke are re - ignited to provide cleaner exhaust emissions.

Here's the firing order:

will what have you checked for dose it have spark , dose it have fuel? if it will not start with starting fuild i would say that you have no spark . go to one of the plug wires remove it from the spark plug install a spark checker you can buy one at any parts store . crank mtr do you have spark. if not check another one that way you can rule out the coil pack still no spark may have a bad crank sensor . at this time i would take it in to a repair shop so they can test that item . unless you want to replace it and take a risk that it may not solve your problem good luck kdc744

I i were you i would check the ignition. it sounds like you are only connecting some of the time. And yes it is very normal to hear the fuel pump kick on when you turn the key to the on position.
