i just swapped the head off my h22 and i set the timing and the firing order is right but it starts funny and idles choppy now im wondering if the fact that im not running the knock sensor has something to do with it but i didnt have one before due to the fact that clip sheared off. i have the skunk 2 intake mainfold on it and the str 70mm throttle body as well. does ne one have any suggetions o and i know its no the icm in the distributor cause i just changed that
