Gas on Spark Plugs/and Rusty????

Okay, for those of you who missed my first post on this Friday...here goes..
I go to start my car in the morning..and it will barely run..BURPS...FARTS..PUTTS...whatever! I begin to think its the MAF..so I unplug it and it still has the same issues.
I drive it for about 1 mile..when the ASR light comes on and the CEL comes on...I pull over again, plug the MAF back in and drive....and the CEL begins to flash...
I get it towed to VW and they cant work on it untl tomorrow. So my friend and I go out this morning to pull the coilpacks and plugs to see if there is any corrosion or gas in the cylinder and on the spark plugs...
Well, there is!! We pulled the 1st coilpack and there is a small amount of "white" junk on the pack...could be some type of lubricant , not sure?
So I pull the plug, and low and behold there is gas on it! I could see the gas, it wasnt "dripping" off, but it was coated, and you could totally smell it!!
So , my question is, am I 100% sure its a bad coilpack..? Because the electrode and tip of the plug was RUSTY as well...Could I have bad gas? It seems as if water somehow got on the plugs?
Why else would they RUST? Anyway, anyone who has had similar issues and has a possible answer let me know....Thanks, Ron.

I don't know what's causing this. I'll take a guess though. Do you only have the problem in the mornings? Or maybe when it's damp out? That would make me think it's wire/cracked coil.
That's all just a guess..
Any way the wite stuff you saw was probably conductive lube, or anti-sieze lube. It's probably nothing to worry about, well unless it's in the engine. Or maybe if it was only on one cylinder.
The plug you pulled had gas on it because the combustion chamber filled with gas, then the spark plug didn't ignite it. This happense repeatedly very quickly, so there's a lot of un-burnt gas in there.
What end of the plug was rusty? That's kind of scary because it means that something has been going wrong for a while. Anyway, here's a link with pictures to help diagnose problems with spark plugs. Hope it helps, probably just a bad coil.

Sounds like you have a blown head gasket which is allowing coolant to get on the plugs causing them to rust. j/k
