I've been having some idle issues after installing a new painless mass-air engine harness and Ford racing computer/mass-air sensor combo on my '86 5.0L that used to have speed density. Ive checked fuel pressure its at 40 pounds, re-set the TPS to .98v. Recently I just found the hose that goes from the underside of the upper intake to the PCV valve is cracked so tomorrow im going to replace the hoses and the valve. im wondering if this could have been my problem. Also, im trying to figure out what this vacuum connection is on my throttle body. Its a 3/8'' connection and ive got it plugged right now. I looked through a few books and found that it is a PCV valve connection supposedly. Is this true? Im really confused as to where the PCV valve connects to. Any help much appreciated.
