My 95 corvette just started running bad could it be bad gas?
Has anyone used one of these tests before? It looks like the ethanol is where it's supposed to be, but is the gas and water supposed to be cloudy after it separates?
I got gas at Costco last weekend, then drove 3 miles home. Three days later, I took it for a ride, and about 17 miles into the trip it started idling really rough.
Now, when I start it, it idles fine in Park, but runs really rough when it's in gear and when accelerating.
Do you park in a garage or carport. If not did you have any rainstorms after purchasing the fuel? If your gas fill drain line was clogged could have allowed water getting into the tank. Issue could be a number of other causes like injector issues

I recall that when I first started driving, there were a couple stations around town that had a reputation for "bad gas". Some of these were older stations that probably had seepage into their underground storage tanks.
Some performance issues happen gradually, but sometimes they just come on suddenly. I would check a few other things starting with your fuel pressure.
