Wish i new the year make and model of this van, the firing order changes on the tears and makes,i will check the 3.4 engine and see what year and who made on e and if the firing orders are the same, a 3.4 engine with coil over plug or you have three coils that each one feeds two cylinder,ignition system,okay ive checked and there are two that i know of and that would be an oldsmobile silhouett or a chevy venture van, heres the best way to know which coil it is if you are facing the engine there are three cylinders in the front and three in the rear, look at the front ones the cylinder in the middle is cylinder # 4, follow that sparkplug wire to the coil and thats the coil, i think me telling you this way is better because i dont remember how the coils are set up in the engine, this is the easiest way to tell you, here a diagram also to help,we have a engine misfire - johnjohn2_16.gif

Hello Mudgoat.
You didn't mention what year or model.
But the coil configuration on the 3.4 liter is the same on all.
Here is a diagram of the coils with the module below them.
Note on the module below the coils that there are two plugs on one end and one on the other.
The 1 and 4 coil is on the end of the module with two plugs.

This should solve your question.
Thank you for using FixYa.

    Looking at the front of your vehicle from left to right : rear plugs will be 1, 3 and 5. And the front plugs will be from left to right 2, 4 and 6.

02 Chrysler van 3.8 came in with blown head gasket and a check engine light for misfire no1 cyl. Installed new head gasket new rebuilt heads plugs wires started up still misfire 1 and now 4


erratic compression indicates a cam lobe problem or cam follower problem
with that many miles on it , the cam shaft will have wear on it but the rest of the motor will have considerable wear including possible ring problems on the numbered pistons
If the body is rust free consider a new -out of the box engine as a cheap plug to stop the repair waste of money

2004 Sorento began with code P0305, cyl #5 misfire. Inspected and replaced plugs, wires, and coil pack on cyl #2. Repair shop told me cyl #5 injector bad so they replaced. Still has misfire.I suggeste


If you had code P0305, I don't know why they would have done anything to the #2 cylinder but if they have already replaced the plugs, wires and injector; here are a few more items to check:
1) Check connections from ECM. Look for any corrosions or bent/broken pins.
2) Check the fuel line pressure
3) Check the engine compression
4) And if the above are good, then you will probably have a defective ECM

Miss fiers multipul times durring drive check engine light has been on constant the van was pluged in at the dealership the reading was cyl 2 miss fire


Misfires are not very hard to deal with. The good thing is that you know what cylinder the misfire is coming from. Try removing the spark plug from that cylinder and see what condition its in. If you have not replaced the plugs in a long time then its time to do a spark plug change. Another cause related to that misfire is it continues is the coil itself. The biggest misconception with check engine lights is that most people think that it will pin point the problem. It does not pin point the area, they just give you a general idea in where to start looking for the problem. Having that said, check the coil and determine if its good or bad by checking the voltage. If all that fails then you might want to check the injector for that cylinder.

Hope this Helps!

1998 Park Avenue: it may not be getting fuel how can i verify this??...


the easiest and fastest way is to listen for pump activation when you turn you key to the on posistion turn your radio off turn the key to on (just before the point of starting)and you should be able to hear the humming or vibrating if you dont then you are not getting fuel. if the pump is working or you cant tell if it is go to the fuel rail look foe a cap that looks like a valve stem cap take this cap off and push the stem in if you get fuel then you know that you donthave a fuel problem if you dont get fuel to the rail then its probably the pump. hope this helps you.

My Chrysler 300m is misfiring on the 4 cyl. Check engine on.


hello, The 300m's all have individal coil packs for each cylinder. They pretty much sit right on top of the spark plug and have a long boot that goes down into the head onto the spark plug. If you have not replaced the one on cylinder #4 I would do so and that will probably fix your problem. It is held down by 2 torx screws. They are around $85 bucks at the parts store. Hope this helps

Misfire on number 2 cyl


Cylinders are numbered from front to rear (grille to firewall) passenger side: 1-2-3, driver's side: 4-5-6. Firing order is 1-4-2-5-3-6
Did you check by pulling #2 out while the engine is in idle to see no weakness from the engine? BTW your coil pack cost $80.
