sunday i picked up a 1990 toyota 4runner V6(3VZE i think?)
the truck runs great, 189k and it purrs like a kitten. the only thing i noticed is that the 2 times ive had it on the freeway, i can smell burnt rubber. i know its not from the tires, the belts all look good. i just had a OC, tranny flush, diff flush, and coolant flush.
the burning smell was before and after the maintance i did, i thought flushing the coolant may work, but it diddnt.

any helP?
