    Default lumpy idle on a 2.2(z22se)

    as title in the morning when i first start the car it has a real lumpy idle,and the only way i can stop it is to rev the engine for a couple of mins,could someone please tell me if the 3rd injector problem relates to my engine or not, also what could be the cause of this i have cleaned the throttle body and egr,also the car feels sluggish when under load cheers in advance.

    Hmm Well one thing I done what seemed to smooth out the idle was when you took off the throttle body Did you have a look down in to the Intake Manifold?

    When I took my TB off the intake manifold was covered in a black tar like substance took me a while to clean it out but done it all and it ran a lot better

    Other then that have you tried injector cleaner?

    I have heard of the 2.2 Direct Z22YH having problems with the Coilpack I would say just check your plugs first as its only a 5 min jobby could be your sparkers.

    to clean the Intake manifold I just took off the throttle body and the hole that was left there I sprayed carb cleaner to loosen it all up then put a cloth down there tied to a stick as my arms are not thin enough and just swobbed it all up.

    I gave it a good clean took my time but was worth it
