I checked both MAFs and swapped others in to check. Is there any way to test for a bad Selin translator? I've only had mine about a year, but I don't know what else it could be it at this point. I know its not anything to do with the IACV. It idles perfect, and it only starts to hesitate when I touch the throttle. I have no vacuum leaks, but unfortunately I don't have consult or anything like that (I really need to bit the bullet and get it soon though). It seems a little crazy, but could I have messed anything up when I was resoldering the connections to the IACV? My ECU is only throwing its usual code 34 for the det. sensor (There has been a short in the main harness since I bought the car).
