    I could go thru the list of all the items I have checked and adjusted in order to improve idling and still can detect what appears to be miss firing. I have tried Techron and so far it is the only thing that has shown some improvement. My question is: does the cleaning of the injectors by removing them and sending them off really work? Does it really make that much difference? I have saved the procedure that was published by one of the members which explains the method clearly with excellent pictures and I feel I could follow it. Your feedback would be appreciated.

    A short video of the issue would say more than a thousand words.

    I pulled mine had them done my Mr injector and power coated the rails. It made as marginal difference.
    Did you check or clean the IAC valves?

    Cleaning the injectors should be done with each major. When was last major? This will also be able to track down any cracked hoses etc which can cause erratic idle.
