A while back there was a hesitation thread about sc400's during take off. Now I was talking to a ecm tuner guru who said that heat sheilds and other metalic vibration and rattle noises can cause the knock sensor to retard that timing on the car.

So i was thinking, to anyone that has a diagnostic tool, will it tell you what the knock sensor is doing while you drive the car? OBD1 and OBD2 are different I'm sure, my 95 is obd 1, and the diagnositic port is on the intake manifold, and another is under the left side of the dash. My Snap on scanner will not hook up with toyota 1 adapter, something just doesn't quite fit correctly, the adapter is too large.

Anyone want to check this out?
