I have a 1993 Pontiac Bonneville which is a 3.6L V6 (i believe) I live in Boston and my nephew has this car in Maryland for college, so I cannot be certain of engine size. I have two questions 1. The car runs hot when in stop and go traffic but as soon as it hits the highway with uninteruppted 50+ mph is cools right down what could the problem be - no fluids leaking. 2. Is there a way to find a good, reliable and fair mechanic in Maryland from the internet.
