I HAVE A 2000 CHEVY CAVALIER 2.2L AUTO. it stalls/cuts out while driving so bad that rpm gauges drops to zero . no check engine light . I've replaced fuel pump, fuel filter, coil packs, plugs wires, knock sensor crank sensor , what else could it be next thing im going to replace is probley fuel injectors

 

Not there looking over your shoulder, but it sounds like an electrical issue.

 

when you say cuts out while driving is it at a certain mph or slowing to stop decelerating from highway, or accelerating at any point. neutral switch on shifter if there still is one, or ignition switch-segfault and I agree sounds electrical now that you replaced all that other stuff already. but alot depends on when the stall occures
