I changed the spark plugs because the van was stalling (no check engine light). It is still stalling and now it's blowing bllue smoke. I had a small leak so we tightened the seal underneath.
Not sure what else to do.

Is the blue smoke from the exhaust? Also, are you sure you got the plug wires back on in the correct order? Have you checked for vacuum leaks?

Let me know.

Yes, the blue smoke is from the exhaust.
My nephew actually changed the plugs, so I'm not sure. All I know is it wasn't blowing blue smoke until after he changed the spark plugs. LOL
How do I check for vacuum leaks?
Thanks so much!

First, I'm concerned about the blue smoke. If the engine is running rough, have him recheck to make sure the wires are on the correct cylenders. Next, check the catalytic converter. See if there is a good bit of pressure from the exhaust and when the engine is hot, look at the converter to see if it is glowing red. As far as vacuum leaks, there are hoses that distribute vacuum from the engine to other components. Basically, look for damaged, broken, or disconnected hoses that may be causing a leak. If the engine is running, you may hear a hissing sound.
