I WAS LOOKING TO BUY A 1992 VR4 FROM A FRIEND OF MINEBUT THE PROBLEM ITS HAVING IS THAT IT WILL IDILE UP TO 3 1/2 TO 4 THEN IT STARTS TO STALL OUT ALL THIS WHILE DRIVING, SOME TIMES IT WILL GO PAST 4 BUT NOT PAST 5
WHAT CAN I DO

 

find the leak that it has, because im pretty sure thats what it is. There must be an air leak somewhere
