Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
This code indicates a fault with the manifold absolute pressure sensor.I have seen the Map/Iat sensor fail and cause this code here and if sending false signals can cause poor running as well as the fuel smell you have here.I would have the engine checked over for any vacuum leaks and if any are found the affected leaks need repaired.If these are all checked and found to be o.k. I suspect the map/iat sensor at fault needing replaced.There is a test procedure to verify this is the cause here if you want I can post it here for you just let me know.
