All of a sudden, no power. Engine is running fine. A/C was running (THANK GOD! it's 101 today!) Everything was working fine except the accelerator. At one point I put it to the floor and I got some RPMs. Limped home to find a P0120 and P0121. New TPS. Looked them up and there are TWO kinds. One is a $90 part and one is a $360 part. Which one (or both?) do I need to replace?
