Ive replace the distributor and cap and rotor and plug wires and plugs. Ive reset the ignition timing as well. All wires look good but here is the thing. If i reset the ecu it takes 2 days of driving before the light come back as well.

What else can cause a code 9 that i have missed or should try?

Oh sorry i though i posted it

BRING JDM_SOHC TOO..spread the word it worx

Code 9 is either a:
P1381 - "Cylinder Position Sensor- Intermittent Interruption"
or
P1382 - "Cylinder Position Sensor- No Signal"

Start by checking the wires INSIDE the distributor, its most likely a loose connection. Double check the wires on the CYP sensor AND the CKP sensor.

Hope this helps, goodluck!

I have tried a known good distrubitor with the same results. but my dizzy in the other car does not throw a code 9. So i can say 100% it is not from my dizzy.

Failing that im going to cut the existing wires to c4 and c14 and re run them outside the harness.
