Message	My car has had hesitation for years now. After I installed injectors it's even worse now. My vacuum is around -480mmhg down to as low as -431mmhg at idle. It sounds like it's misfiring...but it still pulls and drives great...probably better if everything is fixed. I've tested for leaks using the intake tool...the only leak I hear is from the dipstick hole and of course that doesn't count. What's worse now is it sometimes hunts for idle when it's cold to the point where it damn near dies and then comes back and shoots up to 1200rpm like the ecu is trying to compensate...then the oscillations become smaller until it starts to idle kinda normal. The damn car has no codes and no corrosion. All of the cylinders fire. What can possibly be wrong?
