Both run great. No rough idle, no smoke. But the Kansas wind pulling stock trailers has the 2009 acting up. When it does fuel filter life will go from 99% to 0% even with brand new filter. 2007 is just a standby now.
Fuel filters were replaced and collapsed fuel line by trans replaced. One truck has been doing this for 40,000 miles other one just started. Dealership is claiming injectors...just seems like an injector problem would get worse in 40,000 miles
Company trucks both have same problem...pulling loads they both give codes and ho to reduced power ... One is a 2007 and one is a 2009...I have done bottle test and got nothing both are around 170,000 miles. What are acceptable balance rates for injectors?
