So I have been noticing more and more in the last few months that when I go uphill there is a burning smell that comes into the cabin of the charger. I have an 08 se 2.7l, and I notice that in one spot in particular where I get on the freeway most of the time, I experience the burning smell. In this particular spot, I get on the freeway and immediately have to merge with traffic going uphill, so I hit the gas a little bit harder. When I do this I notice the smell, and when I get over the hill and layoff on the gas pedal the smell sticks around for maybe a minute or so and then goes away. I know that this could be several different things, so I'm wondering if anyone else has experienced this problem or might know what it is. Thanks in advance for any input.
