If you have an injector problem and need to replace them, don't buy from the dealership. They wanted to charge me $7500 to replace mine. Not know that I'm a mechanic, helicopter, car, truck, Industrial Mech/ tech. I went to diesel Logic in Jacksonville, Fl. $2000 to reman.,$2500 for replacements. If you buy them from the dealer they are all remans. Diesel Logic also test them for $30 to see if they are bad first if you want that service. The Ally is the easiest diesel to put injectors in.Just make sure you have a shop vac with the smallest tip on it to clean the port out when you take the injector out.
