Rev383 Posted July 4 Report Share Posted July 4 Are the boost solenoids important on these cars? Quote Link to comment Share on other sites More sharing options...
TexasQuest Posted July 5 Report Share Posted July 5 Are you talking about the one the wastegate lines connect to? If so, I deleted mine long ago when I installed hard piping. Quote Link to comment Share on other sites More sharing options...
Rev383 Posted July 5 Author Report Share Posted July 5 (edited) The three nipple one going to the map sensor and it’s next to the map sensor. I’m wanting to simplify the vacuum hoses and seems like that can be deleted but it did causing idling issues for my car. I did not cap them I ran the intake to the map sensor and it ran great but wanted to die at idle Edited July 5 by Rev383 Quote Link to comment Share on other sites More sharing options...
TexasQuest Posted July 6 Report Share Posted July 6 You have an 86-model year if you have a map sensor. Sorry mine is an 88-model year that doesn't have a map sensor. Completely different vacuum hose routing. Quote Link to comment Share on other sites More sharing options...
psu_Crash Posted July 6 Report Share Posted July 6 (edited) Intake to the MAP should be fine. I ran my 86 like that for years because, like most, I broke a nipple off that solenoid. I don't remember what other line comes off that. Should be a diagram under your hood to chase it down, then decide if it needs a vac reference.

Rev383 Posted July 7 Author Report Share Posted July 7 I figured it out thank you all. I broke the solenoid nipple when I was redoing my hoses found the upper side had a weird valve I think it’s a reefs valve. It was messed up couldn’t blow or suck through so I vented it atmosphere. It runs so much better full boost no hiccups for now. 1 Quote Link to comment Share on other sites More sharing options...
