So, I have been chasing a slight stumble.
Hadn’t ever checked timing on my 89 GT that has 40,000 original miles.
To my surprise when I hooked up the timing light to number #1 cylinder I had no spark (or very weak) except when it cranked prior to starting (push start) with spout in but, as soon as it starts and runs spark is almost non existent. All the other cylinders seemed ok.
It’s not the wire as I swapped it with #2 which had great spark and still same.
So, surprisingly when I pulled...
Little to no spark at cylinder #1 with Spout in.
