Propane smell coming from my truck

I have a 99 Tacoma and when driving i get a smell almost like propane. Any ideas to what it could be?

Thanks,
Mark

 

You running propane?

 

No, that's what stumps me....anything that would smell similar?

Where do you smell it coming from? At idle, from the exhaust, or hood proped with engine running?

 

I smell it when driving(windows down or up with ac on), usually when I'm going up hills.

was a diesel truck in front of you?

 

There's a leaky propane tank in yer car bub.

 

LoL... I can't imagine anything smelling like propane. Check for leaks around your valves/heads. Are you smoking your clutch?

 

Wasn't smoking my clutch. I'll have to check around the valves/heads.

I have a slight leak on my rack and pinion, could the power steering fluid be dripping on anything to heat it and make it smell?

Haha nope!

 

Since you have noticed the smell, has anything changed?

Either you made a change or something no longer functions as your used to?

 

No changes were made to the truck, and everything works flawlessly. I'm stumped on this one..

Have you had it on a lift since the smell started? preferably with it running?

 

Wud you have for dinner the night before?

Sorry, cant think of anything helpful.

 

Quit eating so many dairy products. The gas will subside.

 

go to the doctor and have your schnoz checked out!

 

I have a 98 and have experienced this before too.

 

I get the smell usually going up long hills. I think its just gases other cars and our trucks release. My dads tundra has had it too.
