my current tune and idle scan will be attached ,
i think my spark advance might be off. its really really boggy. and i just cant get it dialed in . i would really love to hit the pedal and it to respond and just go and its not. im really frustrated. it might be running rich or lean. i dont know what to do.
another issue im having is .. when i come to a stop the idle wants to rev up and down sometimes low enough to where it dies.
