Unidentified Smell when accelerating

[BigBerky]

2015 Edge sport. Strange smell coming through the vents when accelerating. 90,000 miles. What could it be? It also seems to have lost some power accelerating from a stop and passing. No lights on the dash. Starts fine and seems to idle fine. I’m looking for some input before I take it in to the shop. I don’t hammer on throttle much so maybe it’s been a slow performance loss over time.

Smell is normal.  Exhaust.

there have often been problems with the exhaust flaps behind the rear bumper, if this happens even in recirculation mode.  not usually on this platform, but something to check, especially in areas of high insect activity or high levels of mud/debris.

 

heavy acceleration cuts off the normal emissions monitoring to save the engine, and the fuel mix runs rich. results in odors.

 

if you have a broken flex pipe, that will exacerbate the problem.

Thank you and I have read about the exhaust issue. I’m probably looking at 2 unrelated issues. Next step is to read the codes and determine if my plugs and coils are shot. I’m not sure if worn out plugs would kick out a code, but we’ll see. Probably a good idea to do the plugs and coils anyway at 90,000 miles.

thanks again for the input!
