buick TPS problems

Hello!
I had to replace TPS in my PA 93 - everything was fine for 2-3 weeks - now something is wrong with it again.Why?

Regards

Are you sure the problem is your TPS (again)? For some years, the TPS is adjustable, not sure about 93. I don't think it adjustable for that year. What is it doing?

TPS requires adjustment once installed in that you must setup the idle ot read (not sure the number) 5 volts from that point the CPU will calibrate everything based on sensor information including the TPS for performance.
