Yes. I have a very noticeable exhaust smell under heavy loads or acceleration. And only at probably 35 mph or more. But only with the rear windows out or top down. This allows the exhaust to circulate into the cabin.just found this thread, and have the same hiccup thing - reproducible at the same spot in my daily drive in 3rd or 4th gear at 45-50mph (I have the 3.6 non-e-torque with MT)
curious if anyone with this problem has also noticed severe exhaust smell when putting the engine under heavier loads (e.g. climbing long steady hill on highway) in 3rd and 4th gears? wondering if these are related. it's almost a clutch burning smell (under high loads, not the hiccup) but there is no noticeable increase in rpm at a steady speed (50-65mph).
I believe this is due to the enrichment that happens at higher RPMs, just above our hesitation or "hiccup" in the power band, and at higher load. If you go dig up the threads about the 3.6 torque curves and the threads about aftermarket programming, they talk about the enrichment a bit .
I don't believe that this is a problem per say... It's just something that we are in a unique position to notice.
