I have a 95 3vze auto. I replaced the motor with a rebuilt 3vze. Since the engine swap, the engine or tranny will jerk and the CEL flashes on and back off in les then a second. Hard to explain but basically, if I am cruising at 70 mph @ 3200 rpms, the engine bucks, the check engine light flashes for a second and the rpms bump to about 3400 rpms. When this happens it is just a split second. I have not had any transmission problems. It acts as if it slips for a split second and the CEL flashes. Any help is appreciated.
