| Hello! I am in the process of fixing some vacuum leaks on my 1990 NA and considering deleting the AIV and EGR systems. I was looking at the following diagram and have a question: [ http://img202.imageshack.us/img202/8963/navacuumdiagram.png ] What's the point of the PRVM solenoid on an NA? Could I just remove it entirely and just loop the FPR to the vacuum port right next to it and cap the port on the intake tube? Thanks!
