Engine high-pressure cleaned, now rough running and CEL

[Cees Klumper]

Thanks oldironsights, my no 6 coil looked like new but my guess is the water from the cleaning got to it and combined with heat or whatever pushed it over the edge, I reckon it was weak to begin with (these are the original coils with 100K miles on them). Ordering some spare ones to have on the shelf for when the next one goes.
Some interesting parallels, since I also ride motorcycles (Husqvarna 510 SMR and Husaberg 550 FE, and I commute to work on a Honda 300 SHi motorscooter) and have four match pistols rather than rifles: a 50 meter Russian free pistol from the sixties, a Steyr air pistol, and Walther and Pardini .22 pistols.
Drove the S80 about 150 miles yesterday and never skipped a beat, sure feels good to be able to troubleshoot and repair oneself. Had I taken it to the dealer here in Geneva, I would have probably been out a multiple of the $150 they charged me for the new coil ...

OUTSTANDING!
I do not replace coils or injectors until faults or fatigue sets in. Then I replace the entire set. I have seen original injectors with over 300,000 miles & even original plugs & coils with over 300,000 miles. Miles. Not kilometers.
These were on American trucks. Not the most fuel efficient, but quite rugged & forgiving.
You were correct to associate the coil fault with the steam cleaning. Always check the simple stuff first.
I wish the southern US gulf south was as cool as the central Swiss highlands.
Was 72 degrees F @ 0330 CST on the way to work & 92 degrees F @ 1630 on the way home today. The asphalt & concrete soak up the heat & reflect it back at you. Riding @ 60 MPH to nearly double that does little to cool one down on a motorcycle.
I will take the S80 to work in the AM. Much more comfortable & relaxing. I can sip fresh coffee & listen to tunes while not having to worry about injury if I collide with a boar, coyote, deer, alligator or another vehicle.
Your free pistols are quite rare & exotic here in the US. Mostly Ruger, S&W & High Standard 22's over here. 22LR being the most common. Some of those free pistols are chambered for 22 short.
I have shot pistol matches before. I was badly shamed. I can win with rifles but have yet to win a pistol match.
Your Swiss rifles are so sweet & easy to shoot. The straight pull is fast & smooth.
