Kris , just give the boot a 90 degree twist to free it up from the cap and then pull the boot straight off. Some are on pretty snugly but they come off . If you really have that much trouble getting them off then remove the fan and fan shroud first, then remove the dist. cap with the wires attached, then take your resistance readings from the terminals on the backside of the cap. Remember the plug wires are solid conductor so they have very little resistance in them, its the ends of the wires that have the resistance in them. 5K in the plug end and 1k in the Dist. end for a total of 6k ohms resistance on each wire.

I’m guessing it’s fuel/spark related fault. While driving it can be fine one moment and rough the next. The gas in the tank is good (refilled it with 98 RON petrol), the fuel filter was changed around 15,000kms ago, I checked all the spark plugs and they look fine.

I’m up to checking the resistance of the spark plugs leads and, I know this sounds easy, but how do you pull the leads off the distributor? I got the top one about 20% off (number 2 cylinder), but it doesn’t move easily and I don’t want to break the connector of the lead. I’m just wary about doing this because I haven’t mucked around with the ignition before.
