Default 2003 suburban

I have a 2003 suburban 4w/d 6.0L motor, it continually alarm codes the throttle body sensors not matching. Every dealership I have gone to says I need a new throttle body, I personally replaced them and the sensor comes with it. Within less than 1k miles it alarms again, last dealer wanted $11k to replace and reprogram, last repair shop $650.00. I now have 3 throttle bodies in my garage, (all GM products), no one seems to know the real problem. I have written nice and bad letters to GM and also have heard nothing. My wife has a '99 Tahoe that still runs with minimum maintenance beyond the typical age related items but I will not look to GM for anything new, I only respect my "70 GTO!
