I have had my msp(injen intake, magnaflow exhaust) just over 2 weeks now and yesterday I took it on its first trip. When I got to my destination I noticed that with the cluth all the way in the idle would be very rough and would drop to 100-200 rpm and would stall if i did not put it in neutral which also idles very rough with sporadic idle drop. With the a/c on it is a lil better but still rough. Today while i was driving i put the clutch in from 2 to 3rd and it completely stalled and continues to do so!...i need to know if its vac leak or iacv or ecu related
