Hi sifus out there, pls enlightenme whats the problem with my engine lately, im using 4g63t evo 3 and im having bad engine stalling problem now, ive no problem when smooth crusing and boosting but the problem came when i off pedal and clutch release to neutral and brake engine seemed to stall and if lucky is rpm dropped to the lowest point and slowly climb back. When ive done at my side now is i took out IAC and replaced another and try and also my bov...both of these dont seem to have problem ..i also dunno whats wrong now..
