I had two codes a p0031 bank1 sensor1 02, and a p0328 ciruit high input bank 1, or input 1 knock code. I replaced my bank 1 sensor 1 02, due to the wires being sheared, and shorting the sensor out, and the 02 is now fine, and I also replaced my knock sensor. Figuring maybe the knock sensor just went bad, despite everyone saying they usually dont. Well, the code went away for one night, and popped right back. My car runs great, until it warms up, then loses about 15% power, and stalls out when hot every trip I take it on, then the slip, and vdc lights pop up, and it takes about 4 seconds of cranking while pumping the pedal to start again, and the lights remain on, while killing my power by about 30%. I am thinking maybe a CPS, or I dont know, all my wires seem to be fine, and I cant figure out what circuit high input, bank 1 or input 1 mean. I'm sorry, but I've searched everywhere for info, and the stealerships around here are jackasses.. Any help would be greatly appriciated.

possibly have a short in one of the wires again.

 

I also went through every wire, and did a test spraying brakekleen completely around the intake areas seams, to be sure there werent any leaks with the car running..

 

UPDATE: My CPS code finally popped on, got the sensor, and fixed it.. I knew I was right, the light just didnt want to show up for a few weeks..
