passenger side bank = no fire! help me out please...
hey guys, i just finished up my lifter change (used stock heads/cam) and now my entire passenger side cylinder bank is not getting any fire!
the car runs suprisingly smooth, and the idle does not change at all when you unplug the main coil pack harness from the passenger side valvecover
the fuel injectors also do not seem to be pulsating to the touch like the driverside bank is either.
what could be wrong? anything i can check? i simply unplugged the coil harness and the fuel injectors when i was dismantling everything, never touched the PCM at all.
i was puzzled and never imagined it was only running on 4 cylinders! it was just soo smooth! when i tried to rev it it would stumble pretty bad though.

Doesn't some of the upper class gm vehicles now shut off 4 cylinders when at cruising speed to save gas? I know I read about this from a car magazine.

well my fuse panel cover stickers are so distorted, i cant really read them. if you are standing beside the driverside fender looking into the engine bay, its the box on your left, and the top left fuse. it was a 15 amp small fuse in my car.
i went thru checking them all and PRAYING for a blown one
it seems like when the spark was cut, it was just pumping unburnt fuel to the O2 sensors, which were screaming "holy **** its WAAAAY too rich" to the PCM, thus, shutting down the fuel injectors on that bank
the reason the header tubes on that bank were heating up a little bit, but not anything like the driverside, is because it was still compressing the air, just not burning it, thus, making the tubes heat a little bit.
