When I park the jeep and turn it off, the engine sounds really rough. Also, I smell fuel. It starts and drives fine, although I sometimes think it may be underpowered. Oil pressure, temperature, and tachometer all show normal values. Any suggestions? ---

Year? Motor? Mileage? When did last get spark plugs and other maintenance info? It sounds like it is dieseling on you, which shouldn’t happen on a fuel injected motor. Is this an older jeep with a csrburator? ---

Pull the oil dip stick out and smell the oil. If the oil on the dip stick has a gas odor, the problem might be with a leaking fuel pressure regulator. Tester ---
