Coming home a week ago after a pull up a long hill hard in 2-3 I changed into 4th and with still some incline left my K11 started to shudder/stutter losing power, changed down and it went away a little, but then got worse as I got towards home, last few corners and it just felt down on power and would shudder/jerk/cut in and out bad in 4th.
Found some overly worn plugs (1.4mm gaps with nice round tips) and very dirty fuel filter and replaced those, also bad white corosion and worn pitted edge rotor button in dizzy, cleaned replaced those, took a test drive yesterday and it was actually worse, this was with new plugs and filter and cleaned dizzy cap.
Someone suggested fuel pump but during checking of filter etc I primed a few times getting like 1L or more with an ignition start prime, and it sounds ok.
Car will generally idle just fine, but on the test drive power was still down and the shudder when trying to hold it in gear and give it power was very bad, like cutting quite forcefully in and out, never making any real power in any gear now.
What I did do today was find the coil specs in the Haynes, primary is like .8ohm secondary 1.0K ohm, on testing mine I could not get the inner dust cap off, but from what I could measure from got 1.3 on the primary and 11.7K on the secondary, I'm hoping maybe I found the issue? (unless I'm measuring it wrong).
If nothing else can someone tell me what the secondary measures off a known good coil, and if a high resistance can or will cause the car to cut out so badly under load like mine is?.
(On the test drive it was cutting in and out so violently I had to slip the clutch to make it back up the hills to get it back home again).
Current personal theory is if the secondary is so high it's just not giving enough spark under load, yet with the primary okish it will start and idle fine, as it's getting signal and needs very little spark to idle or rev at idle with no load?.
Right now considering ordering a complete dizzy or replacement coil off ebay in the UK, locally in Australia the price would kill me, need to get my car back driveable asap.
