I have 99 mirage that had a bad TPS (according to the downloaded codes) so I changed it. Car worked great for 3-4 weeks. then began sputtering again and the "check engine light" came on again, you guessed it, TPS again. has anyone had this problem before? I need to know what is causing theTPS to go bad. Something has got to be bad in the system causing them to quit. any help would be appreciated.

It was probably just a defective replacement TPS. Over the years, I've seen quite a few parts DOA or failing within a short time, most often with lower end aftermarket brands but sometimes even with OEM.

I'm not wild about AZ parts. Too many stories about defects. I prefer to work with, in this order, OEM, Standard products, and NAPA. They usually cost a bit more but this stuff is too hard to do twice.
FWIW
YMMV
