My van misfires and blows smoke?
Drove my '91 Aerostar to the library for half an hour, running fine. Came out to start it, and it sputters and misses and blows huge clouds of blue smoke. It responds to the throttle by revving up, but doesn't smooth out at all, as though it is only running on two or three cylinders. Won't idle without a little pressure on the gas peddle. After a couple minutes, I shut it off and walked home. Any ideas what might be wrong?

Being that it is older, you could have jared your coil pack. That could cause misfire, could also be an o2 sensor, or something in the computer messed up. There are more problems that could be, I'm not 100% sure based on the info given.

Sounds like it isn't firing all the cylinders. Check the spark plugs. The bad ones are wet or sooty. Maybe it rained while you were in the library and the distributor got wet. Basic troubleshooting will answer the questions. Discussion will not.

Sounds like you blew ur headgsket or burned out a valve. either one could cause those symptoms. Looks like you will be pulling an engin apart either way, unless u just junk it.
