MacTR Posted November 1, 2010 Report Share Posted November 1, 2010 Help! I get anywhere near 7-8 psi and my car falls flat on it's face. Roll on the throttle, is not so bad. Tromp on it and it spits, coughs and jerks like crazy. Link to comment Share on other sites More sharing options...

Caliber308 Posted November 2, 2010 Report Share Posted November 2, 2010 (edited) secondary injector? Does it do it at appox: 2500 rpms?? I don't think it is a Vacuum Advance problem. If it was, it will only buck for a split second at appox. 2500 rpms, and then continue boosting.The quickest way to find out is to cap the V.A. port on the distributor, plug the hose going to it and take it out for a ride. By the way your describing the problem, sounds like the Secondary injector is not providing enough fuel on heavy boost at 2500 rpms which is when it kicks in.
