I went to autozone to check my Engine Service Soon light. I have problems with shifting and have
high Rpm's at idle at times. The code is PO122, the TPS sensor. How difficult is it to replace the TPS myself?

Its simple just mark the old one before you remove it and set the new one with the markings you made with the old one.
