Hard to advise you when you do not say what year it is therefore do not know things like EFI or carburetted or ignition matter etc.

SOURCE: Rear cylinder not firing

The first thing I would do is replace the spark plugs again. You can foul a plug and it will cause you more problems than you can ever imagine. I see you have done all the logical things that I would recommend but I did not see you have replaced the plugs after the 200 miles. You would be surprised at how many times a $2.00 part can cause fits beyond belief.

SOURCE: no fire at the plugs, battery fine, was running

Your Sporty has a fuse box somewhere. check the fuses to see if any are blown. Harley always puts their ignition systems on their own circuit. If you don't find anything that way, contact me directly at wd4ity@bellsouth.net and I'll scan a trouble shooting chart in and send it to you. There's more to the late models than there was with the early models.

Switch the coils to see if the fowling switches, if it does its the coil.

SOURCE: 2000 honda 1100 shadow spirit. Rough idle, little power.

Replace the spark plug caps and try again. On Honda's the cap is often part of the wire (a dealer part) NGK makes some inexpensive plug caps about $5 each. They should OHM out to 5000 anything above or below and you need to replace them. This should fix the problem.

Changed plugs and wires and put on a new igntition coil and it is stillmissing on 2 cylinders


I believe the Mustang has 3 coils for a V6, and 4 for a V8, each coil controlling two cylinders. First you need to check and find which two plugs are misfiring, and if they go to the same plugs. It may be that more than one coil is defective and the coil pack needs replacing. With the vehicle running pull one spark plug wire at a time to find the missing cylinders. If the engine slows or starts running rough, that cylinder is firing, if you pull the wire and there is no change you have found your missing cylinder, from there trace the wire back to see which coil it plugs into. Also, make sure your plug wires are not touching each other and are in the spacers the factory installed. If you still can not find the problem it may be in the main computer. Most autoparts will run a diagnostic check for free.

No spark to rear cylinders runs good and then runs on one cylinder 1986 honda shadow 1100


try switching the position of the two coils, the plug wires will unscrew off of the coils and that way you dont have to pull the spark plug wires too,(be sure and change the 2 wire couplers too) if your front cylinder stops firing you know its the coil, if the back cylinder still doesn't fire then your coil is good and you either have a bad #2 spark unit or a bad crank pulse generator.

I have a 2000 virago 250 ran perfect for the first year. Then lost power. you pull front plug wire off while running it dies instantly. pull rear wire off it still runs rough. if you leave wire close to...


Are you sure the rear cylinder has good compression? Did you check the two cylinders with a compression gage? The compression should be within 10% of each other. Check the ignition timing of the rear cylinder. I will bet the valves just need to be re-seated on the rear cylinder.

What order do the spark plug wires go in on a 2000 kia sportage?


Basically the coil pack in the rear of the engine feeds cylinder #4 and there is a a plug wire off of that coil pack also that feeds cylinder #1. The coil that sits toward the front of the engine feeds cylinder #2 and the plug wire coming off that coil pack feeds cylinder #3. Each coil pack has a white plastic connector that can fit either coil but the length of the wires to each coil is different and should be easy to distinguish which coil pack each connects to. -cylinder #1 would be at the front of the engine and cylinder #4 would be at the rear.

Cylinder number 5 is misfiring. Check spark plug, spark plug wire and ignition coil for the number 5 cylinder. The number 5 cylinder is the closest to the front of the car on the drivers side. With engine running in dark (at night) take a spray bottle of water and lightly mist spark plug wires and coil and look for arcing. Autozone will test coil for free.
