yea i know where the crank angle sensor is...
well to me it seems like normal but i guess with the error codes i though if i could get those fixed it could make the car run faster?

idol is perfect. everything runs seems like normal... but on std boost i dont feel much pull... but on 15psi its a different story

Manual says:-

"The ignition signal in the primary circuit is not entered during cranking or running"

Check items:-
Harness and connector
power transistor unit.

Other that replace the items it tells you to check, it'd probably say take it to your nissan dealer. :wink:
See if you can get hold of a known good power transistor from someone and try it on your car.
