    can injectors cause this?

    EDIT: FIXED! Plug your ICV's in kids :p



    Ran fine with 17lb injectors. swapped to 21lb with a chip, and this started. I tried a spare 413 ecu with stock chip and had the same problem. It's possible that something came unplugged/undone while messing with the intake, but the only thing that I've changed are the injectors.

        hmm my guess, not really know M50 is motors. Is the ICV or cold start if it has one? sounds like gas is fluctuating so Id assume the mixture is not right. Id even maybe say fuel filter?


        Please leave feedback below, thanks

          I just can't imagine the ICV or the fuel filter going bad all of a sudden when changing injectors...

          I do have a new fuel filter though that I've been meaning to install.

          edit: also, notice the coolant temp gauge waves a bit. It's like it looses all power then catches itself. Very strange. All grounds are good AFAIK

              Hmm interesting. I suppose I can try swapping back to the stock injectors to see if the problem goes away... What a PITA.
