does it smell like brake/clutch, oil, antifreeze, plastic? they are all pretty distinguishable! for brakes sticking, after you park car go and touch each wheel see if ones alot hotter then others (be careful could be very hot!) i know mines got a bit of a antifreeze smell cause the plug on my thermo housing is leaking a tad! for plastic or maybe rubber check your belts and timing belt/cover! could be rubbing!
