My engine runs very cool around 45 or below mph. When I am on the highway around 60-70 mph the car will go from 1/4 temp up to 3/4s in a matter of 5 -10 mins. Any ideas on what it could be? I did hear some slight pinging going up a hill around 60 or so. Do you think at this mph it could be to advanced? I have it set to around 14 ATDC. What about cooler plugs? Thanks.
