I own a 2007 LT3 Tahoe with 26000 miles on it. Picked it up Nov 21 st 2007

Ok so we went on a trip from San Jose to Yuma Arizona to pick up a 16' Toy Hauler. On the way back My Wife rolled her window down and Yuk it smells like propane gas and or Sulfur BAD!! We were at a Gas station so we thought it was their filling station. Later on she opened the window and Pow again.

I thought it may be because we are towing the trailer and Srug it off.

So today I am driving home and put down the windows and there it is again. I am not towing I am going 45 mph and the smell gets really BAD!! I need some help here. What do you think is causing this????

I am going to bring it to the dealer but don't want to get charged. Since I am out of my 1 year warranty. It is a motor related subject and I have had the trannny reworked already since 1st went out already.

+I am Pissed!!!

Thank you,

Hugh

 

Sounds like you need some beano to get rid of your gas problem lol! It doesent sound like a vehicle problem why would it smell like propane when its fueled by gas im assuming?

 

Might want to get the cats checked.

 

the sulphur or S02 could be the cat but the propane smell could also be a heavy grease getting hot like wheel bearing grease this could also be the sulphur smell too
