After days of troubleshooting i have found that whenever theres a current being draw, all of the engine sensor voltage go out of range or spec. For example at idle everything seems fine, but whent the radiator fan comes on you can hear and feel the misfire.

Another example is when vtec kicks in, the engine bog or hesistate real bad. It only hesistate right when the vtec solenoid draws the current. It does this on every gear.

I'm pretty much stuck on this electrical problem.
