I just looked at my timing while the car was cold and got about 16* vs 4-6* when the car is heat soaked and running poorly.
at the lip or the ribs?
are they smaller than the Mach 1 alt pulleys? my old stock Mach alt pulley measures 2.75 at the lip and 2.5 at the ribs. if his is 2.5 at the lip he could be over-spinning it, assuming they are supposed to be the same size as the Mach 1.
You can. But expect a CEL at the very least. And possibly the computer going into some kind of limp state.
I recall someone unplugging the sensor and wrapping it up with foam padding of some sort and leaving it in the valley.
What else besides knock sensors can pull my timing so low?
