Default Wont run right

I have a 1994 C4 w/13,000 miles. I keep it on trickle charge during winter months.Pulled it out to just run it the other day.
When i start it the volts read 15 then drops down.
I,ll leave it running after 5 mins. starts missing a little.
Pull it out down drive way starts running rough.
Put in drive punch it starts breaking up & popping.
Then hard to start volts read 11.9-12.3 on dash gauge.
When started it bucks & misses,wont stay running.
Any help?

Based on your description it could be anything.

Engines need 4 (technically 5) things to run:
Air, Fuel, Spark, Compression, and Timing of all of them.

I'd start with fuel and spark.

What is your fuel pressure?
Do you have good solid spark at the plugs?

Troubleshooting requires a logical process not merely guessing. Start simple and gradually get more complex in your search.

1st thing to do is run that old gas out. And while you are driving stop at Autozone advance wherever and have them check the battery. If you haven't changed anything on the engine the odds are they are OK.

'stayble' sorry bout the spelling, it keeps gas from turning to acetone.

Huh? Gas line anti-freeze is basically an alcohol and last I checked not that much different than ethanol. They both ABSORB water. I bet you have water in your fuel.

You should store the car with the tank full to minimize condensation with lots of Sta-Bil. I would double dose your car or drive it.
