  • Advice on injector readings

    Hi All

    Just picked up a 2007 GX with 231k on the clock an no service history, so im working thru the gremlins and after all the oils, air, water im onto the fuel system and done the filters and new lines.

    Im getting some black smoke from the exhaust when under load up a hill or put my foot flat so id like like some opinions on these reading as im still learning about diesels but from what ive read here in the forum i suspect these injectors are well overdue for replacement.

    Cold
    1- -2.2
    2- 2.3
    3- 0.7
    4- -1.1

    Hot
    1- -2.9
    2- 3.1
    3- 0.6
    4- -1.6

    Thanks

    Less than half of the information usually required to give an opinion.
    Based on those, it's enough to say injectors are shagged.
    If they are original very flogged out.

        When you done the oil change, did you check the oil pickup screen in the sump for blockage? Extremely important to do this given the year of the vehicle, no service history, blowing smoke and ordinary injector fb values.

        Your vehicle has a customer service exercise to replace the injector seats free, what i done is bought the injectors myself cheap (from ####) and had Toyo replace them during the injector seat CSE so all labor was free as they had to pull the injectors anyway. It's one way to get the problem solved as cheaply as possible.

          Hey everybody,
          These little links don't work well for me, it's too small.

          If you post via photbucket using image code, it's looks bigger & better & we can see it

            The oil pickup was pretty mucky but yes it was done. I didnt know the injector seat replacement CSE applied to a 2nd hand vehicle, thanks for the tip.
            I dont mind replacing the injectors myself its all part of the learning curve and a vehicle i enjoy working on.
