    Hey guys need some HELP!! My car is a ae86 running a 4agze from a ae92.
    It was running fine till I got a front mount installed now it stalls when ever I let go of the accelerator and allow it to rev low ??? It also makes a popping noise when the supercharger kicks in, also when the car is off there's air still going through and pops near the exhaust manifold too ???

    You might have a vacuum leak.

    So it has a hunting idle? its due to the length of the intercooler lines,
    How big is your cooler?

    bov is pretty pointless on a SC motor.. speaking from experience.. any FMIC on a 4agze that is relatively stock.. isn't a good idea.. its put down to your intercooler piping being a little too long...

    do you have an aftermarket ecu???

    there are few ways around it.

    1) get a small ass intercooler and exact to stock length pipes..
    2) get an aftermarket ecu , i got the mircotech.. and set the idle at 1100 and it solved this problems..

    are you running a thermostat?? i would assume this problem is even worse when the motor is cold?..
