i have also done a ICM test which is in another post.

 

Hopefully it is bad connections. Check that the wires are clean. Otherwise it is a bad ECU.

where is this though? ICM, spark plugwires or coils?
also, does stage 1 corrispond to coil 1 or L1/E1 on the ICM
stage 2 corrispond to coil 2, L2/E2 on the ICM ect?

I dont feel any misfire while im driving.
it hasnt got a rough or gumpy idle either.
i only thing i have noticed is that the car will slightly vibrate once i hit 60mph.
so, this isnt a major thing but im just after some information on them codes.
