Engine Performance problem
1993 Buick Regal 6 cyl Front Wheel Drive Automatic 240k miles

This car has done this for some time. Its a 3.1.engine. Only certain times it will hesitate or try to quit running very quickly, more so accellerating up a hill at any speed, and sometimes will be fine. I have replaced-- tps, iac, ign. control module, coils, plugs/wires,pvc. I know its with ign.because using timing light there is a pause in light when miss occurs. Also there is no diag. code set. Thanks for your help.
