I had this problem with my wifes car. I went through the car top to toe and found more than one problem causing this intermittant issue.
I found a weak crank sensor, when warm it was intermittantly losing a signal, replaced it and the problem was a little better, I then found that the throttle position sensor was also intermittantly not within the range it should be, replaced it and it helped, I then was getting the oxygen sensor code and that was only due to the car stalling, nothing to do with the o2's, I finally traced the final issue to the integral harness on the valve body inside the transmission, I replaced that harness and fitted a new transmission speed sensor and the car has been perfect.
I know you have several issues here that could be your problem but you now have a base to start from.
Last thing is the car may just need an engine set-up if you are no longer having any codes. This is only done by the dealer using there WDS computer system. The perform a oxygen sensor orientation test, they set-up the kick down and also set-up the Throttle positon sensor (TPS).
Hope this helps.

the only thing that can change the air from hot to cold, or vice versa is the blender door. under your dash is a box which has 2 compartments. one with your heater core which is hot and one with ac which is cold. the blender door basically diverts which on the air in your car is being drawn from. if it is cold, air is moving on the ac side. if its hot, air is moving through the heater core side. if its warm, the door is in the middle. your temperature control knob is conecteted to an actuator, which moves that door. the actuator is a motor, but if it goes out, the door will be stuck on whichever side it is on. i would check that first. hope this helps

Hi there, Might have good news for you if you have an x on your transmission picture and your bulb picture and if the light goes off with the rest of the other pictures there is nothing wrong with either. In the manual, the bulb and gear box has an x through them and all the other pictures are exactly the same as you see when you turn on your ignition. Again, if all the lights go out after a couple of seconds everything is fine, if there is trouble a picture would stay there, hope you follow this i have had a couple of wines. Cheers
