experiencing gradual power loss and worst mpg
Beginning to notice a gradual loss in power and poorer MPG. We all know that a new timing chain is in my future,but no codes have be thrown yet. My car is an 08 with 22,000 miles. Sure wish it would pop a code before I take my little 2500 mile trip in november, would hate having to get a timing chain replacement while on road. Maybe I should drive the car more often than I do now and maybe a tad more aggressive, may do the trick.

Try a fuel injection cleaning if that doesn't work then the timing chain. Its a lot cheaper and would benifit the vehical anyways

Actually, check your oil. Low oil will make the car sluggish, one of my pistons actually froze up and used a lot of my oil and blew my engine at 39k miles
