This is acting normally then...

I guess it really depends on how cold it gets outside as well as how high the RPM's go...
If your RPM's are above 3500 RPM's then I do suspect something is wrong, and further
info is needed...

My friend's 2001 Hyundai sonata does this. I found out many issues with the car, most of the issues were censors. It was the main issue in the Hyundai... Try scanning the ecu for codes, it will tell you something.

Smoke smells when ac on nissan sentra


The speed control of your fan has resisters that are in the venting system to blow air on them to keep them cool. If they overheat and or burn you will lose your low and medium speeds of the fan. If you run the fan at full see if the smell goes away. Your engine could be burning oil on the outside of the engine block, make sure that the weatherstrip where your hood meets the fresh air intake grill is sealing tight.

It seems you have a timing problem. Have the engine timed properly. If that does not work it could be a craked rotor or distributor cap. have all these checked.
