Just got my WSP y-pipe installed yesterday, and today I noticed that there is a fairly strong fuel smell in the cabin and blowing out the heater vents. Could this be caused by improper re-installation of the o2 sensor by any chance?? Maybe the chemicals on the y-pipe they use for the mandrel bending?? Or could it be the infamous leaky fuel lines because it just got really cold this week??

HELP!!!

But could the o2 sensor have anything to do with it. I searched and came up with something about the fuel running too rich if the o2 sensor is not working right and can cause fuel smell. Is there a way to tell what the problem is for sure???

Your O2 sensor is fine. Your Y pipe is fine. Replace your fuel line, have a nice time. Stop thinking up things that don't make sense in your mind. Look at my rhyme, it's not worth a dime.

Your O2 sensor is fine. I have a 1991 max and i had the same problem, especially when its cold.
If you look into the front right side of the engine compartment (around where the spark plugs are -- you will find a fuel line with a hose clamp on it. This hose clamp is notorious for coming loose, which in turn causes a very small fuel leak -- tighten it .
It is very difficult to get at -- you will need a long phillips screwdriver.
This should solve your problem.

What about on my 89 max SE? I have the same prob? I do have the haynes and chilton books but what specifically should i be looking for? Location? What is the cost and time frame to change?

YOUR PROBLEM COULD BE EXACTLY THE SAME. THE ONLY WAY I FOUND ABOUT IT WAS FROM A MECHANIC FRIEND OF MINE.
LOOK IN THE ENGINE COMPARTMENT FROM UNDER THE HOOD - AROUND WHERE THE SPARK PLUGS ARE, NORMALLY ON THE RIGHT HAND SIDE - YOU WILL SEE A FUEL LINE - WHERE THE METAL LINE IS JOINED TO A HOSE USING A HOSE CLAMP. YOU MIGHT ALSO BE ABLE TO SEE WHERE THE GAS IS LEAKING (VERY SMALL LEAK). YOU NEED A LONG PHILLIPS SCREWDRIVER TO TIGHTENEN THE HOSE CLAMP AS BEST YOU CAN.
INCIDENTALLY, MAXIMAS ARE ALSO NOTORIOUS FOR RUNNING RICH ON COLD START-UPS.
BUT IF YOU FIX THIS PROBLEM, IT SHOULD TAKE CARE OF MOST OF THE PROBLEM.

That's a good temp fix, but honestly on a 12 year old car I would replace all fuel lines I could, taking off the intake manifold and replacing the injectors and giving the manifold a good cleaning, etc.
