Have replaced tps, icm no change. Could it be that the pcm is bad. We are getting approximately 160 mile to a tank.

I would try first resetting the pcm by dis-connecting the battery or using the proper scan tool with your OBD connector below the steering column. The return spring, the body and throttle blade may be bad and a bad vacuum leak or sticking cable could cause this. What fault codes are you getting now and after you do the reset. Let me know, ok. Please drive it only if you must.
