hmmm thats wierd.. not too long ago while diagnosing a no start 
condition I ohmed the left set of injector wires and the right set. 
they came out different values so I assumed they tied to 2 different 
points. Its possible for there to only be one driver and for the 
injector sett to be tied to a signal selector or something right??

More evidence: why is it I don't hear one "click" in unison.. if you 
grab ahold of the front injector on each side at idle you can feel 
alternation. maybe its psychological because I *thought* I knew what 
was going on. geeze wierd. batch sucks. glad I didn't polish the TPI 
base to a mirror now. Someone make a RPM based variable delay box to 
insert onto the injector harness and give us SFI!
