Hi all, Drove up to the Sierra's Sunday and the engine was pinging (detonation) as a heavier load was applied going up the long grades. Finally at about 4,000' it was getting warm so I pulled over and let her cool off. Decided to head back home. Drives great on flat (even in 105 degree heat with the AC on), but with a load it pings and temp increases. The heads were reportedly done not long ago and look relatively new. At the last smog check it showed timing right on. I was running premium gas too. Did have the roof rack and kayak on the top but that should not contribute (much). Other than this it runs great.
My wife says if it can't go to the mountains, why do we have it? Ideas? - Thanks, Ben
