On my 2008 Town & Country, the check engine light came on. Autozone tells me it's the EGR valve. There has also been smoke coming from under the hood once the van has run for a while. Smoke stops within a minute or less of shutting down. Anybody else have this? Wondering if the light and the smoke are related, or if I have two separate issues. Help!

 

Prob 2 different issues
