Not available here, AFAIK.
This is OK since it wouldn't be any use to me anyway, partly because theres nowhere to plug it in, mostly because I wouldn't trust a local mechanic, (and certainly not a parts store operative, if there were any), to do it.
The above are mostly success stories, but I console myself with the many expensive wild goose chase stories I've also heard.
I do have a Colortune though. Could also use a Tach/dwell meter.
