strong exaust/fule smell when cold... Not after warming up. Check Light on.

I would start with check engine light diagnosis.

Hello, Scan for those trouble codes. The check engine light lets you know there are codes present. Those codes are vital to home diagnostics, and nothing is going to be solved without them. Let me know, and I'll either tell you the issue, or let you know where to go.
