Tonight I rescued my car from my inlaws driveway. It has been there for two weeks, and we have had HEAVY rains nearly every night. I had an umbrella cover on it, but water still found its way into the engine compartment.

So when I start it, it is hard to start. I figure its just mad at me for abandoning it for 2 weeks. I get it started, and it is idling perfect. I take it for a drive to the gas station, and when I come to the first light the engine tries to die. I get gas, and bring it back to my inlaws for dinner. When I park, I let it idle. It will be idling perfect at 1000, and then drop off and sound like it is only running on 2 cylinders. If I blip the throttle, it goes back to 1000 for a few seconds, and then drops back and starts missing again.

When I drove home (~30 miles) its popping through the carbs like crazy when I am on the idle circuit. Give it gas, and the popping goes away.

So, what is it? Clogged idle jet is my guess. Probably not water in the gas after a 45 minute drive. Water messing with some other thing?

You might have seen it in my "new 914" thread. Up here, it's the ethonal that kills carbs. Stupid stuff will gum up those little passages in a few days.

I had good luck with the "Stabil" product. Few ounces each fill up did the trick. I'm sure there are other and even better products, but that worked for me.

I forgot to use it on just one tank, it took less than 100 miles to get gummed up again.
