trouble code p0320

this code is for two successive erratic Profile Ignition Pickup (PIP) pulses this can be caused by a few things

Loose wires/connectors.
Arcing secondary ignition components (coil, wires and plugs).
On-board transmitter (2-way radio).


Another thing I have noticed is some cars with under drive pulleys have had problems where the crank pulley will come loose and cause erratic crank sensor readings

I would check all connections from the crank sensor and all wiring.
