the first thing to do is fix what you know is wrong... which is the o2 sensor, then figure out the tps issue.. then if your problem is still there.. thats when you would start changing out spark components and checking other things.

I would say the idle thing was the tps.. but it could also be the o2 sensor when your car goes into closed loop.

I picked this up from another forum.. almost makes it seem like the o2 sensor is causing the tps code. I would definately fix the second o2 first

"From what I understand, the coolant temp sensor for the ECU decides the open closed loop opperation when you first start the car. After its warmed up, its in closed loop reading from the o2 sensor. When you floor the car and it sees a WOT from the TPS, the ECU reads a preset map and ignores the 02 sensor. As far as I know, open/closed loop only applies to the temp of the engine and it reads preset maps when its floored. Under normal driving it uses the o2 sensor to calculate the cleanest A/F ratio for the environment.
