Could be an A/C coolant leak.
Your 1996 Escort might smell like gas when it is not running because of a damaged gas tank or damaged fuel lines. Leaking injectors or a leaking tank can also cause that smell.
if your asking about your air conditioning, it could be your refrigerant, but a smell that would more closely resemble vinegar would probably be your coolant
Your fuel pump is probably really dirty and your fuel injection probably needs to be replaced. I had that same problem with my 96 Tahoe and when i would idle it would reek of fuel. I went to get all those things replaces, and not only did the smell go away, but my mpg's went up about 3 or 4 g's. take it for a tune up!
If you smell antifreeze, there must be a leak somewhere. Have the cooling system pressure tested.
Brown suger in your diet can cause this smell.
The trans mission IS probably going out. This is a well know defect in the 2002 Tahoe. Google it.
Either you have a blockage present or your vents on your sewer lines have become blocked or you need to install more vents.
If the top is left off of the container it would smell up the whole house.
bad or failing alternator
driving it to roughly
Type your answer here... I had the same problem with my 96 Tahoe.. Vortec 350. Problem was a blown intake gasket.
This would depend on your nose. A bad CMP sensor may cause improper burning of the fuel and can give a smell out the tailpipe. Will the CMP smell? Never. A Ford camshaft syncronizer will squeek and could cause a metallic burning smell.
Something you ate was rotten
Cause its burnt.
I would say they smell something...
running a marathon
The magnesium anode rod inside the tank
yes nd it will also give of a oily smell with it
Propane has been given a sulfur-like smell for leak detection.
bad wheel bearing may cause it
is it damp under or near the dash ? if so its most likely your heater core cause it will cause a very bad smell that would be first thing I would check
Most of the time it is caused by a hole in the heater core, do you smell a sweet smell? The sweet smell would be the antifreeze.
