And to top it off, 3rd gen 4runners are from a different time, the fuel injection technology has progressed a lot. I've had 2 people comment about how smelly my cars exhaust was, even though my 4runner is well looked after and passes CA smog just fine.
Because it goes away, if something is leaking it's probably a leaking exhaust rather than fuel. Check under your manifolds heat shields for cracks. You could test it and see if it's to the point where a carbon monoxide detector would sound.

Oh ok gotcha, yea I do typically go out during the cold months and let it run for 5-10 minutes because I just figure since it's an older vehicle, I should let it heat up a little before driving compared to newer cars where I'd check an email, pick a song and leave 1 minute after start-up lol
Sounds good though, I'll take a look at the exhaust components just in case.
Thanks for the feedback
