Q: Vibration at idle, Low Rpms, Fuel smell at the rear, no Codes

asked by on September 26, 2017

To start off, i have no codes. I have a vibration at idle and while driving the car kinda of runs not as good as it use to and While in park you can smell fuel at the rear of the car but there is no leaks.My guess something in the fuel system going bad but not bad enough to give me codes and might be the reason its giving me a rough idle and have low rpms. Also my gas mileage got worse. Ive clean my throttle body, replace map sensor,o2, purge solenoid sparkplug, ignition coil, cam shaft sensor.

My car has 103100 miles.
My car has an automatic transmission.
