My injectors are under the valve covers which would make it a MAJOR surgery to get at them....I suppose I should bring it to a dealer to have them test out each injector

If all that doesnt help i would spend the 100 bucks on the warranty deductible and have a diesel tech look at it

I've been told that every time you add an aftermarket product on the engine you should disconnect the batteries for at least 15 min. that causes the computer to reboot and with the new products. I'm avg. 17.5 mpg city, and yes aftermarket air filter is a must also look into a tuner.
