If chain tensioners and followers have broke down then chain can jump cam time and cause power and idle problems. I tried to look for an estimate for you in the estimator link but does not show. Price depends on shop and your area. When you get estimates make sure you compare apples to apples and see if estimates include same parts and labors.
