i was driving home from work like every night and i smelled something weird in the car. i looked down at the gauges to see if anything was wrong and the coolant temp was pegged at the bottom. i pulled off to check the coolant and everything was fine, no leaks or anything. i started it up and then the tach died and the weird smell came up again. i was thinking that a fuse blew but the gauge and backup light fuse was fine. any suggestions would really help.
