Firing order mitsubishi 3.5

Mitsubishi Montero 3.5 V-6n24 valve

Looking from the front of engine to the rear on the passenger side 1-3-5
Looking from the front of the engine to the rear on the drivers side 2-4-6

The engine has coil over plug with coils only on the drivers side. The spark is shared via spark plug cables to the plugs on the passenger side. So If you are replacing the spark plug cables:

#2 cyl.coil drivers side shares spark with #5 passenger side-
#4 coil drivers side shares spark with #1 passenger side-
#6 coil drivers side shares spark with #3 cylinder passenger side.

What causes a cylinder to mis-fire (or not fire, whichever is the proper term for it)? I went to a friend of mine's house who has a code reader, because the service engine soon light came on, and when...

is the code P0304?

just to clarify the passenger side of the engine compartment is the right side, the drivers side is the left side. I know it is backwards. It is easier to refer to the right/left as passenger/driver so everyone is on the same page.The cylinders from passenger side to drivers side are 1-2-3-4

I think the covers you are referring to are the coils. There should be two coils and two wires. The coils are usually held in place with a bolt(s). A 10mm socket is the normal size socket used to remove the bolt(s). Once the bolt is removed and the connector is unplugged you should be able to pull up on the coil and it will come out.

There are a couple of things you can check. The first thing would be two remove the spark plug wire from the number four plug. check for spark out of the plug wire with a spark tester (available at your local parts store) if there is spark than you may have an injector issue or a mechanical issue (possibly low compression).

If there is no spark than remove the spark plug wire from the coil and check for spark out of the coil. If there is no spark out if the coil than swap the two coils and see if there is spark. If there is spark than replace the coil without spark. I know that is a little confusing so if you need me to clarify a little I can, just let me know.

Let me know how that pans out. If you have any question let me know.

1999 Toyota Solara V6 SLE has an engine misfire, Throws check engine codes, is running lean in bank 1 any ideas?

running lean bank one; suggest a bad 02 sensor on bank one,check engine light on? suppose so, or you would'nt have codes.may be a bad coil pack on bank one. it does'nt run without a backfire right? your best thing to do is this. check engine fire to plugs that supply fire to bank one,it may have a red fire to plugs on bank one side, but you need blue fire to plugs on bank one side.[the best spark to plugs will always be blue] you may only need to replace part of the engine coil pack, they will have numbers on them[coil pack] and which cylinders that they supply spark to. if i'm not mistaken, you will be looking from front of car, look on passenger side of motor for a bad spark plug, or may even be a worn spark plug wire,inspect your spark plug wires for a worn place where the wire is exposed to ground the spark from the spark plug. pull the spark plug out and check it for carbon build up also. for carbon build up, it will be covered with hard black substance. recommend if you do replace plugs, nepindenso, no ac plugs[cheap] no ac delso,cheap. the better the plug, the better the car runs with great mileage. hope this helps,merry christmas, and as always,if you need further assistance,please repost your question and an expert will be happy to assist!

#8 coil pac, cylinder misfire...Need diagram The mechanic says I need a coil pack and spark plug replacement for the #8 ...Need diagram to figure out which one it is. it is

The #8 coil and spark plug are located on the drivers side rear of the engine. You will need a 7mm socket to remove the bolt that holds the coil down. After the bolt is out, pull the coil upwards and remove. Next you will need a 9/16" spark plug socket to remove the spark plug which is located in the hole that the coil came out of. The spark plugs in a 5.4L engine are sometimes frozen into the engine. If it is very hard to turn the plug, try spraying some WD-40 down the hole onto the plug and let it soak in for a while. Do not try to force the plug to turn, it will break and a special plug extractor will be needed to remove it.
Hope this helps you!
