Is there anyways to check the injectors to see if there working right or stuck open or somthing? My fuel mileage pretty much blows right now, I did an oil analysis about 4,000 miles ago and it came back good on fuel, and Im gonna be doing anther one shortly in the next week or so to see. But is there anyways to check them?

when you say your oil analysis "came back good on fuel", do u mean there wasnt fuel in your oil? or the opposite?

if ur injector was stuck open, there would be a TON of white smoke out the exhaust and a LOUD knock from the engine.

what kind of mpg's you seeing?

The analysis came back with with fuel was less than .5%....... Silicone was higher than it should be but we chalked it up to the AFE torque tube. Im gonna do another analysis when I change me oil in the next week and see what it says. Im only getting like 16-17 highway, and 14 or so intown, but this last tank was horrible and I don't know why. but this tank im on now seems to be back up, right now im at 150miles on just over 1/4 tank.
