So I tested my TPS and it was out. Normal is 0.9v at WOT and 4.7v at closed. I had 0.6v at WOT and 4.3v at closed. I adjusted the TPS to within normal volts and the car ran way better and idles around 8-9 hundred rpms now. All the power is back thanks for the help.

I have a JDM 93 WRX. I have been having performance issues for quite a while now. The car will often not pull hard and have problems accelerating higher in the rpms. If I disconnect the battery and reset the ECU the car will perform very well for a short time then start having this power loss again. I do have the odd misfire at idle as well. I had a high around 1200rpm and after cleaning the TB and replacing the PCV the rpms are now up around 1400 or so. If I shut the car off and start it again the car will idle down to about 1000rpm then when I drive it and stop again the idle is up again. I have replace/cleaned: -MAF -Coils -Spark Plugs(gapped to 0.032) -Knock -Cleaned TB(replaced gasket) -Air/Fuel Filter -PCV -Swap ECU's -O2 -Looked for vacuum/boost leaks -BOV
