2004 Matrix - Two-stroke smell coming from engine compartment
Strong two-stroke mixture smell coming from engine compartment, through
vents into cab of car as well. No leaks whatsoever. Car runs perfect
but the smell concerns me. It began immediately after taking the car to
Oil Can Henry's. They have since done a complete inspection for leaks
or spills and couldn't find anything. The following has been done
recently before a 2k road trip a couple weeks ago: Oil change, air
filter and cab filter change, swapped out spark plugs (reinspected
plugs to make sure there were no cracks etc. Plugs were replaced with
Bosch Platinum 4 prong. Any ideas?

Usually, what you smell inside the car is coming thru the vent from the engine compartment. So it could be a leak around the engine or the vapor canister. Its possible the canister gets overloaded from time to time when the computer vents the gas tank to the canister. A very small leak can be a very strong smell inside the car.
fuel pressure regulator ! $50.location/top right side engine.smells like gas in cab strong while parked with air /heat on . check this. mine started leeking gas after 60,000 miles. easy fix one star bolt/hose/gasket 15 minutes.
check whether the matrix do circulate the hot water. To confirm check the two hoses connected to matrix in engine compartment.Also check the heater valve which is before matrix in the engine compartment.
If you're experiencing a strong fuel smell, there's most likely a leak in the engine compartment. The AC will cool incoming air unless the "recirculate" button is pressed. The incoming air is what has the fuel smell, indicating a leak in the engine compartment. CAUTION: leaking fuel in the engine compartment is extremely dangerous and can lead to a fire. Please have the car diagnosed by a professional immediately.
hello drk...the only time you smell this is when the engine is under a load? Does is seem to be coming from the a/c vents? Any smoke? I've never heard this complaint on the 2005 6.0 powerstroke. A strong coolant or sulphur smell is what most owners report.
Could you give a little more detail please?
