I replaced all those parts roughly 2 years ago, but I've put very little kms on it these last couple of years - maybe 10k at most. I swapped all those parts, and it was driving fine for a good year afterwards before it started playing up. It started out not so bad, I would be driving for an hour or an hour and a half, and then just as I was making my way home it would do this little blip every 5+ seconds, not really bad. It's just got progressively worse now.

I haven't replaced the dist cap, but I have had it off 2 years ago when I replaced the leads and such and it looked pretty good inside. It was replaced maybe 6 years ago I think, but it's only done maybe 25k kms since then. Rough numbers sorry, it's been a rollercoaster ride of life for us in recent years so doing my best to remember things. Think I should take another look and see how it's fairing? Anything I should be looking for specifically?

Look for corrosion.... It's sat so it could be all crappy in there. Give it a clean with contact cleaner and then apply dielectric grease. Worth doing regardless. Do this with wires too... And if the dizzy button is a bit sad give it slight sand with a 400grit paper or similar just to remove carbon or potential crud off it...

Opened up the dist today for the fun of it, rotor has seen better days, points have seen better days... I'll let the pictures do the talking;





I cleaned both up as best I could, didn't have my wire brush handy so it was all sandpaper but used a 400 then a 1000 to get it as smooth as I could. The points in the dist cap have decent pitting into them;





The rotor and point wear wouldn't be the source of a hot-only hesitation would it? Or could it be as simple as a bit of heat expansion causing the contacts to miss here and there? Camshaft sensor looked good, I cleaned all the crap off after this pic and looked beneath it, little oily but otherwise fine;



And here is the cracked coil;



So there you have it! I'm thinking just do a new coil + dist cap + rotor?

Cap and roter are consumables. they are cheap and replacing them rulles something out. That said ive seen worse that were not producing obvious problems. That looks like a OEM coil so its 22 yrs old? prolly about time.

That coil is almost certainly ratshit dude, mine gave similar symptoms to yours before replacement

So is the rotor, and the cap would be a good idea

I have done all of this to my XJ since I got it last year. All new ignition components bar the coil (wires, plugs, dizzy cap and rotor) all new fluids (engine oil, gear oils, trans fluid and filter, transfer case, power steering, brake fluid and coolant), and the passenger mount + gearbox Mount, new rad, top hose and thermostat too. Oh and crank sensor... Goes every time now (did fuel filter and air filter too lol)

Next on the list is DS engine mount, steering stabiliser, track bar and shocks... Refreshing is the best. O2 sensor needs to be done as well as it's @147k now....
