Curious: Did GM change the firing of the fuel injectors after the '93 model year?
Specifically, I'm thinking '93 and older is batch-fire (3 injectors fire at a time, then the other 3 activate) while '94 and newer may be true sequential fire.
Is this correct? Is this why the '94--newer have additional sensors?
Thanks, all.
