[QUOTE="MrGiggles, post: 482497, member: 22613"] You need a DVA to test the ignition. I have little faith in resistance testing. Check the ignition timing, go through the link and sync procedure. You'll need a timing light, someone may have screwed around with the timing stop screws, or replaced an ignition component and did not reset it. Also check the rubber bumpers on the timing screws as well, they can deteriorate and cause the timing to change. [/QUOTE]
