dissonance

After trying 3 different o2 sensors, replacing both check valves, swapping my o2 simulators around. I still get the same codes. Could these codes be related? Both are on bank1. after resetting the computer today what sounded like the air pump kicked on about 4 times for a few seconds then cut on again just for a few more seconds. This went on 4 times before it quit and put p1415 in the pending codes.

I don’t know what else could be causing this? If it where the pump, I would get the codes on both banks. My bank1sensor1 stays around .4 to .3 at idle but sometimes it bounces back and forth like the other. The code p1133 is Insufficient Switching I have got p0133 Slow Response but it has only showed a few times. P1133 shows up about 8 times in a 30 mile drive

i really need some help here <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" />

Well looks like I may have nailed it down. I have a hard time believing this but here it goes. I put both my afs98 that I got with the car in to b1s1 and still got the same code (I have o2 Sims so I had an extra. Easy fix right? New o2? No the new acdelco had the same problem. Tonight I broke down and tried my 4 o2 (afs97) it came from the rear bank2. Put it in and start the car cleared the codes and drove about 2 miles (thats all it took for the other code to trip) worked great no codes, ltrims where right beside each other. I could not ask for any more stable. I am not going to trust it until I get about another 100 or so miles on it.

Could 3 acdelco o2’s have the same problem? 2 stock and the other brand new? I would never believe it. Maybe the longer wire caused it, but the wire is only an inch longer maybe. <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" />
