Back in town, and thanks to Maurice's smart instructions on narrowing down the cylinder #4 misfire problem, I fixed it (new ignition coil) for just $40. The engine is back to normal with the new coil. Nice!
While I was swapping coils to find the problem, I found the rear sway bar had snapped in two near the left side bend. I've now replaced it with a Tarett sway bar (may as well start replacing with BSR legal parts, because...). First question is the little donuts that come with the bar. I know where they go since the TRG bar had them, but what's the point, and how close to the bushing should they be? The only thing I can think of that they do is prevent side-to-side movement of the bar, but can that really even happen?
Pictures and one additional question...
1. Notice the black grease (or something) on the right rear inside wheel carrier. Is this something obvious? What is visible in the photo is all there is (it's not splattered all over the place).
2. Here's the broken TRG sway bar. This is a replacement for the original TRG bar that broke in the exact same location (left rear bend) a couple of years ago.
3. Here's the new Tarett sway bar and one of the donuts (right side) that I was wondering about. (Also shown in the broken bar picture.)
Thanks,
