Same happens to me when I step on it on the expressway. It leaves shorty after though. I think it's just the engine burning the fuel and the sudden change in speed and RPMs cause it so get that smell??

What is your mileage?

I only had this problem for the first few months I've owned my stang. Once I put a couple thousand miles on it, it doesn't smell anymore.

All that I smell now is rubber from the tires

Happens to me too. There was a thread a few months ago on this, it's normal. Something to do with burning off carbon build - up in your cats i think.

 

I think Bigfoot climbed into your engine compartment and died...

4.6, K&N CAI tuned, torque bar, SLP Exhaust

 

I get this all the time too

 

WTF is wrong with your cars. No smell on WOT. Just pure happiness and the natural testosterone smell. Lol

Interesting

 

This totally happened to me for the first time in owning my car for 3 years, yesterday morning. Car has 33K miles. I went WOT about 3 minutes after starting. Ironically, I went WOT to catch up to a 2015 Mustang GT that passed me as I was turning on to the main road, lol. Anyway, smelled exactly how you described. I tried to replicate it a few minutes later when entering the expressway, but I did not get it that time, and I haven't been able to get it back ever since. So, carbon buildup in the cats burning off is a possible explanation, I think.

 

this usually happenes when you buy a new car and you dont let it break in you just start going at it hard from the get go ... get your cats fixed ... by fixed i mean buy a xpipe with a high flow cats and the smell should go away forever !!!

 

I think you're right because I indeed got a little impatient before 1,000 miles and went hard a couple times. I went on a long road trip the day after I bought it through these beautiful scenic drives, totally open roads, and it was just too tempting. Those of you who have also gotten the smell... does this explanation fit for you? And what exactly is the damage to the cats that happened in this case? What other damage might have happened due to going to hard before the break-in?

 

That's incredibly not true. Just stupid.
