i have it in, have the truck running, and the truck is loping extremely hard. i only get it to smooth out by inducing more vacuum (raising idle). And, any small vacuum leak is turnedinto a huge one with this cam iv'e got. So when is big too big? And is this the circumstance? I just can't seem to get my rig running right. thoughts, PPLLLEASE! i want my truck back!!!
