I just recently purchased a 1989 Pace Arrow. It is a 37' RV with a Chevy 454. I just took it on its 1st run and it lacks power going uphill. Which is a big problem here in Colorado. It has 57000 miles on it. The exhaust kinda stinks. When its under a load I can here an air noise pulsing from the front of the RV. But when I am running down the road on level ground it does fine. When going uphill I am lucky to do 15 to 25. Even on slight grades. Any help would be appreciated.
