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

SOURCE: I need to find out where is cylinder# 5 on my 2002 Jaguar X-Type

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

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

1998 Jaguar XJ8 cylinder numerotation:
1234 right bank on the passenger's side, and 5678 left bank on the driver's side.
In other words cylinder five is the 1st one on the driver's side closest to the front of the belts.

Yes, definitely. I just had the same problem on my 97 xj6... car was misfiring, running very rough at idle. My last ignition coil was bad. I had it replaced and solved the problem. Try it yourself first. The repair shop wanted almost $400 to get a new coil and replace it for me. I found a coil at familycar.com for $57. I pulled one coil out and the boot was slightly melted at the end. Be very careful taking them out as nothing is cheap on our vehicles... Good luck!
