I have a engine light on so I looked at the on board computer and it came up with P0401 insufficient EGR flow P1131 lack of upstream heated oxygen sensor switch – sensor indicates lean – bank no: 1 I have run the whole gas line from the back to the front but cannot find a leak or where the smell comes from. It seams to be really bad when the AC is on.

The fuel will evaporate very quickly as soon as the pressure is relieved. Since the air conditioner is picking it up, I would concentrate in the engine vicinity but don't overlook anything. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. loulom New User Aug 23, 2010, 6:19 AM Post #3 of 4 (2425 views) Re: 1995 grand marquis V8 smells of gas can not find leak Sign In I would first like to thank you for your reply. I have tried to find a leak with the engine running but as you say it’s evaporating so fast. Would it be safe to spray a soap solution around the fuel injector and the engine? Or can you suggest another way, as I have no experience with this.

They make leak detectors for finding hydrocarbons but they are expensive. One trick used commonly is spreading some baby powder in the area to leave a stain when a leak hits it. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
