1997 SS CR. I just had the motor out, checked the valves, put in new belts, put in higher compression pistons, put it all back together. Seemed to run well in the garage.
Test ride: Fired it up, warmed it up, and took off. Seemed to run fine for about 2.5 miles, then it started missing and then seemed like only running on one cylinder, until it stalled out on the road. I got it restarted and turned around for home and got about a mile, still running rough like only one cylinder firing, and it stalled again. I let it sit for a few minutes and it restarted, and I rode it the rest of the way home, although on this last mile or so, it was firing on both.
So I poked at it for a week in the garage. It will start and run normally in the garage. Checked the timing with a timing light, checked the synchronization with a Carbmate. Checked the compression. Checked all the grounds (and added additional grounds, and additional wires from the battery to solenoid, etc).
Today, Test Ride 2: A little hard to start, but started and warmed up, took off. Ran normally for about 2.5 miles and then started acting again like only one cylinder. It actually stalled out at the same street at which it happened last week. then it stalled out again on the way back, at about the same distance. And, again, when restarted (after letting it sit a bit) running the rest of the way home, about a mile, it was firing on both cylinders.
Once home, I pulled the plugs. One looked normal, the other (vertical) had a little wetness on it and smelled like raw gasoline. By the way, after it had cooled down a bit, and I put the plugs back in, it started right up and was running on both.
Is this intermittent problem likely just a loose connection around the coil or plug, or an indication that the coil is about to go bad? Not sure how to undertake a fault diagnosis here.
I should add, before I started messing with it, it was running fine.
