Our horn ring is definitely matte, so based on what you’re saying most of the replacements out there will likely work. Is a busted horn ring a common thing? Just curious.

It’s the extreme “loping” idle. The colder it is outside, the worse it is. Yesterday, it was in the mid 40’s and it loped like mad. The other morning, it was around 55* and the loping was a little less vigorous. I’ll try lowering the warm idle speed a bit. Right now, it’s about 920 rpm or so. Not terribly high, but I’ll lower it to 850 and see what happens. 

Also, Jim, we spoke months ago back in Madison about our rusty battery tray. I finally sprayed some LPS 3 on it and the battery mat. It gave off a strong smell for about a week and then calmed down. Then, I needed the heat the other day and it stank like mad for about an hour so before going away. Or else it burnt up part of my brain and I can’t smell it anymore. Either way, should I have any long term concerns about  LPS 3 in the vicinity of the heater bellows/tubes underneath the back seat?
