ok guys so my car has a bad idle with no check engine light on. i have replaced coils, wires, plugs, as well as the iac and blocked off my egr. i did a boost leak test with my homemade tester and bike foot pump. i found leaks at the biss screw and injector insulators, so i replaced both and am no longer leaking from those areas. whats happening is that when my car is warming up it seems to idle pretty steady around 1300rpms untill it warms up to operating temp and surges between 300 and 600 rpms. if i take it for a drive and do a few wot pulls and my car will start idling around 1500 rpms or 2000 with little surging. i also noticed that if my rpms are low and im in neutral, my brakes only work for the first pump, after that i have to push them really hard to get the car to stop, can i be leaking boost through the vacuum booster? ive been at it for about 3 months and one shop couldnt help. im thinking about taking it to satan aka mitsubishi if i cant figure it out
