Changed the coils on 5 & 6 ?

They may not have been the failed ones at all

You may have all 8 bad, after they been in the
motor for 6 years or more

You can not go by obd codes for a cylinder misfires
on a Lincoln L/S

I have a 2004 L/S V8

I do not have the time to type all night & teach a class,
on how to solve that issue

All you can do is walk one new coil until you find the bad one
or several

If you ever go into ETC Fail safe-- do not replace the throttle
body-- it will be a bad coil

As you have tried to do--I have seen a PO300 codes indicate a failed coil

I have used Mode $06 on professional scan tool to find failed coils

I have had to walk a new coil & replace the old one & move to the next cylinder, until all issues were resolved

That car is unique to anything you will have to work on

Replaced coil pack on 3800 pontiac bonneville and its still missing what now?


First you need to determine what type of miss you have. Is it random on all cylinders, or is it restricted to one or two cylinders? Random misfire can be caused by crank or cam sensors that are starting to give out. Single cylinder misfires can be due to plugs, wires, coils (you already addressed those), as well as internal issues such as burnt or broken valves.

Need some more info on some diagnostic codes that came up on my truck & how to fix them. P0137 o2 sensor, P0300 random multi miss, P0303 cylinder 3, P0306 cylinder 6, P0307 cylinder 7


Replace your O2 Sensor and Spark Plug Wires. If you still have the Random Misfire, replace your Spark Plugs, then Replace your Distributor Cap and Rotor. If you still have the Random Misfire you may have a Timing Problem, or Ignition Coil problem.

04' Ram 1500, bad mis-fire. cust repl s/plugs. no help. Codes for coils #7 & 8 w/mis-fire. replaced coils & wire set. Better, but still P0300. Compression good


You still have random misfires (PO300)
You most likely replaced those coils that set a code, and those were not the one bad offender,spiking the computer module.
Take a new coil and put in a cylinder,no change, replace old coil and move new one to next cylinder. You can do that once or twice a day, if you have nothing else to do. You need a 90 degree day, to really get that solved,unless you have an ignition oscilloscope.
Never had a bad spark plug in 45 years.

Miss fire 1 and 5 changed wires and plugs


Probably coil pack. Follow spark plug wire from spark plug to where it plugs in, that is your coil pack.Some are seperatable. Depending on motor size you may have coil over plug. You said wires not (cop) coil over plug boots.If it is coil over plug it is just a boot you changed in that case the coils plug into boots & on plug & an electrical connector. They are seperate for each cylinder.

Cylinder Misfires


It could be your spark plugs or a coil. To see if it's a coil move the coil from #5 to #6 the miss will change to that cylinder with code p0306 and change #1 to #3 and see if it changes to p0303. If it does replace all the coils. You change all coil because if one or two go you know the rest are not far behind

96 bmw 740il misfire


This is a pretty common problem. I would change your valve cover gaskets. They run around ~ 50 bucks. If they are bad it will leak oil into spark plug well and cause a misfire. Very known on the 740.. Also if tune was not anytime not too long ago id change spark plugs while you at it. Then clear the computer and if you still get misfire on 8 try changing the ignition coil which is right about the cylinder with cylinder ignition coil 5. clear the computer. if you get random misfire and misfire cyclinder 5 after then its your ignition coil. parts store runs around 100 bucks
