Check the igniter module.
I assume you have a ecu code telling you #3 coil is missfiring ?
If so also check the crankshaft angle sensor .
If it is not an error code do a compression test and check the injector.
Hope this helps

Compression test first. test injector. Check wiring. If passes u need a live data scanner to analize what could cause this misfire - fuel trims, vacuum pressure, o2 data. Input sensors (camshaft position) And actuator's (exhaust gas recirculation)

How do you fix missfire on cylinder 4 on 2001 s-type jaguar


If you have Individual COP Ignition Coils,then
replacing the bad coil or several coils, if necessary,
should resolve the issue with misfires

You can not just expect the PO304 code to be cylinder
number 4 with the misfire

It may be this time & it may not be,so you need to have it
checked with the proper test equipment

That said, if the car isn't drive in hot weather & at least
20 miles, they may not find the problem or just throw parts
at it, & take your money

Just a couple of things to keep in mind

Your car & some fords have similar issues, as ford
once owned & stole some jag technology.

  • A missfire could be alot of things. If its "pulling a code" then its probably not spark plugs or plug wires. Most of the time it will be a coil or crankshaft/camshaft position sensor. If its a little miss then it could be a dirty injector where only some fuel is getting through. If the injector plugs are easy to access i would unplug #3 while its running. If there is no change, its probably a spark issue and would bring your coil in to autozone or anywhere that can test it. If its good, get the crank/camshaft sensor tested. If the idle gets a little rougher when you unplug #3, it could be a plugged injector

Engine missfire


Get your local garage to put a scanner on the car. The early s-type used to suffer from ignition coil faults. If a fault has been hinted towards a specific coil then swap to a different cylinder and see if the fault follows wich will indicate a coil fault.

Has the vehicle had its spark plugs changed? every 70.000 miles as they tend to fail if left unchanged. Intake manifold requires removing to replace bank 1 plugs.

Also check the small rubber elbow on the end of the plastic beather pipe wich runs throught the intake manifold branches. Elbow is located at the rear of the engine

Hope that helps

2004 Dodge Grand Caravan engine light on, missfire


That is a code for the secondary (spark) circuit on cylinder number 3. It is usually caused by a bad connection between the coil and the plug (take the coil off the plug and check for moisture in the boot). If not, it might be a bad coil...
