92 yukon runs rich

[MSborn882007]

So I noticed when my truck is running the fuel smell is fairly strong. Engine runs fine,no idling issues,only thing is it takes an extra second or 2 to crank when it's a cold morning.gas mileage hasn't really been an issue,went home on leave an got 17mpg highway. I don't know if it has any relation but my temp gets up to around 150-160 when warmed up. Saw on a different forum that sometimes they are related to each other. Any ideas?

engine temps should be just above 195. but the colder it is the more fuel is used. is the fuel smell from exhaust?

Yeah,it's from the exhaust. But the smell is just the same on the warmer days too

sounds more like a converter smell then fuel.

I agree a Bad Cat or O2 sensor would be to blame however I believe the O2 sensor would throw a code

Mine always runs at 180 no matter what I do. I have a 195 degree thermostat in there as well. Any idea what could cause that?

180° verified by what means?

The dash

Ran at 195 until I put in this all aluminum 3 row radiator, then it stops at about 180.

Mine at start up warms up to just over 210 and then immediatly drops to 150 - 160 and stays there

no codes on it,i cut the cat off and just put a flow on it with turndowns.i guess the smell is normal then,just thought it wouldn't be that strong.i have one car with no cat right now an cut the cat off my old Colorado too and neither are this strong.but that's a 4 cyl and a 5 cyl so I guess they just wouldn't put out as much of the smell that a v8 will.would yall recommend anything for the temp or just leave it?i just don't know if its a concern or not
