Can anyone tell me the numbers in which the cylinders are in? Is it 1-6 front to back, or vise verse, or are they random like the firing order? I need to take care of some misfire issues in specific cylinders. Thanks.

#1 cylinder is closest to the rad..

Thanks! I know it's a silly question, but I don't want to have to play a guessing game when putting new ignition coils in.

Jaguar used to number the cylinders from rear to front with the straight six and timed the engine with #6 until the XJ40 AJ6 engine. Then the numbering went from front to rear and the timing was from #1.

I also saw something that said the firing order is 1,2,3,4,5,6. How creative. Hehehe. I've got a similar cylinder misfiring challenge I'm trying to track down. I took it to a mechanic who specializes in European cars and his Snap On Tools monitor gave me 4 codes, P0300 (multiple cyl misfires), P0302 and P0305 (misfires in #2 and #5 cylinder, respectively) and P1314 (Misfire Rate Catalyst Fault, Bank #2). I've heard that a bad calalytic converter can give misfire symptoms and throws off those same codes, so I hope I'm not chasing something with the misfires that isn't the cause. I replaced Coil #2 already and I'm going to do #5 now and then see how she runs.

Yeehaw! Victory. I replaced the #5 coil and cranked it up and it runs smoothly again. It's amazing how a straght 6 doesn't like to run on 5 cylinders. Hehehe

The firing order is 1,5,3,6,2,4
