I have an 06 DE that when I punch it, thers like some burning smell or something I can smell when I have my windows down. Then it goes away. Any thoughts. Smells like sulfer a little

 

Welcome and there could be any number of reasons behind the odor you smell. This is not a usual complaint with the Z. Could be a blockage in one of the catalytic converters, or a piece of debris caught between the undercarriage and a hot engine component. Have you jacked up the car to have a good look? Are there any codes in memory?

 

Look for valve cover gasket leak onto exhaust manifold.

 

i guess actually opening the hood and looking around makes too much sense

 

Well I cant duplicate it while I'm parked. Its when I put it into overdrive

 

definitely your wallet dude. check your firefluid

 

Havent checked any codes. Just bought it so. Only does it when I hit overdrive on 75. Or pick up real fast

 

Someone said it was the sulfer in the gas down south?

 

Will definitely check that

 

Aaaahhhh! Sarcasm!.... The poor mans wit

 

Plastic bag on the y pipe

 

Your Z's diagnostic system will hold some codes in memory, so there could be a clue there. Not sure what you mean by "hit overdrive on 75"? Do you mean the odor only becomes noticeable when you shift into sixth gear at 75 MPH?

 

+1 on this.
