Ever since I bought my runner the exhaust smells. It gets good gas mileage, the tailpipe isnt black but it smells strong. Any idea on a fix? I'm thinking about running seaform through it. Its bad enough that I roll my windows up at a stop light if I'm there long.

What does it smell like? Smoke, unburned fuel, etc. will have different smells and different fixes.

Rotten eggs?

like a gas. but not from the pump. it smells normal. but its very strong. for example if you l parked a car in a garage and then smelled. just real strong.

Is your engine burning rich??

My '91 slowly lost mpg down to 12 before it finally threw a code for the o2 sensor --- there was a very strong gas smell the whole time.
After replacing - mpg jumped right back up to 17-18 without the gas smell.

are you smelling it when the engine is cold?

Maybe your cat is failing.

I get sort of a rotten egg smell when the back window is rolled down.
