300zx tt boost sensor not working and not running right
im working on my buddies 90 300zx tt and im ahving a problem. i resealed the whole motor and didi the timing belt. but as i now have the car back together it doesnt run right. when you get on the throttle the car is ok, but as soon as the vtc engages it cuts up. the boost gauge inside the car is not working and it was before. on that note does anyone have a vacum diagram, wiring diagram, or an fsm? thanks for any help jd.
small hose goes on the end of the balance tube on passenger side for factory boost.Two of the biggest problems on the Z are Boost Leaks and bad idle.. You can make a boost leak detector 3" pipe plug with pressure gauge .. remove air intake and install detector pressure up with air compressor slowly you should be able to hear the leaks. Air Regulator on rear of plenium large hose that connects to balance tube in center.. Use wd40 -- filll as much as possible with eng OFF.
Don't remember since I installed a boost controller (Greddy Profec B) . If you install a boost controller you remove most of the vac lines or plug them.. Also did the AIV, EGR, and PVRP removal when I added my chip upgrade to 91 TT. Later added dual intake , changed cams, chip upgrade, 555 injectors.
