Is your check engine light on? If so, you have codes stored. Get them read at an auto parts store.

 

Smelling gas in the exhaust is a rich running condition. Do Scotty's video, Make your Car Run Better with Spray Cleaner. You didn't give your mileage. Dirty fuel injectors are also a possibility in a 24 year old Ford.


Thanks I’ll do that. The odometer stopped working last year and my speedometer doesn’t work.
