I had my oil changed and now my car wont run right.All my car wants to do is cut out then rev cut out then rev.Its running rich i think because i smell fuel and i see a little black smoke out of the exhaust .im guessing its unmetered air causing it but does anyhone have any suggestions on how or what to look for.

Make sure you look around the area that you've been while doing the oil change. You might have knocked an electrical connection loose.

this all happened after a oil change. did u get it changed by someone or did u change it yourself?

why would you have someone else change your oil? just wondering.

I dunno. I found the problem. Loose hose to the Bypass valve under the powerpipe.
