[QUOTE="Big Sky, post: 660390, member: 3460"] My '03 only ran at two bars only until my first tune-up at 17,000 miles (may have had coolant replaced then, too). I always thought maybe a throttle body sync, which it needed and which eliminated a surging, may have leaned the mix overall a little, making it run hotter. Since then it runs at three bars above 70 degrees ambient, and two bars below. Never see four bars unless city stop-and-go on a 85+ day. It still runs fine at 57,000 miles so I don't worry. [/QUOTE]
