JasonS4 helped me change my plugs...his garage is heated.

So when we go to pull the plugs, they were loose enough to turn by hand from the very start. The dealer was the last to touch them, 40K service.

Some of them had staining on the metal hex part. The coilpacks did not show damage or effects of heat. One of them had condensation in "well"...combustion water??

Anyway, everything is now how it should be. Hopefully no damage.

I broke my leg 3+ weeks ago... I haven't been in the S4 since, and won't be for another month. No winter driving for me this year! I have the gf start it once a week and let it run for about 30 min, no problems she says. Too bad she can't drive stick, I don't think I'd see it again.

I set mine to spec with a torque wrench one time and realized it isn't high enough to crush the sealing washers on the spark plugs. If they don't get crushed the plugs will back out. Either way the dealer techs should know better.

I just worked on a saab 9000 for a guy last week. It wouldn't start. I had him crank it over and removed the plugs to check for wetness (fuel). When I removed the plugs.. all four were hand loose and were gapped at something like 0.058"! THe spec for that car is around 0.035". He said he replaced the plugs and was afraid of overtorquing them. He also said the parts guy told him the plug gap was pre-set so he didn't check it.

The problem was the direct ignition coil pack unit was bad. I can only suspect the wide plug gap was too much for the coil(s). THose things are $350+ for saabs since all four coils are part of one unit..
