-32 is as far as it goes and you are right, it means that the pcm is pulling fuel. When your stft hits -32 you will get a rich code. I would say it is either the fuel driver in the pcm, the pressure regulator, or sticking injectors. I don't know all that much about how the cali pcm works, but I would think if it were one injector sticking that just one bank would be pulling fuel. Excessive fuel pressure would make both banks go rich. I would check that first (while the problem is occuring). Like I said before, you can check the injectors with a mechanic's stethascope (~$8.00). It is pretty simple. You just touch the end to each injector and listen for a clicking noise. If you touch it to an injector and don't hear clicking, then that injector is either sticking open or not opening. Checking the PCM- only one option for that, and I would tell them that under no circumstances do you want any TSB updates installed on thier.

Also: Check the ground strap going from the pcm to the firewall and make sure the connections are tight and clean. Also try swapping the fuel pump relay with another one.

 

Here is the recoreded data. It showing the fuel being cut from one side but, I could sworn that I've seen it cut both sides. I'm going to go out and record it again. IT was funny as hell because it started to do it so I tried to hook up the scanner. While I was hooking the scanner in I could hear a hissing noise that kept getting louder and louder. Well ignored and started the recording man was the truck pissed off. it was backfireing and sputtering like crazy. Well when I got onto the road whenever I let go of the gas the truck would continue to speed up and thats when I relized that that hissing noise was the IAC opening up and now that it was opened all of the way the truck was driving stupid. It took the whole drive home for that damn thing to reset. Anyways here is that data. I'm going to take it to a mechanic feind off mine so that we can look through the fuel system.

Refresh my memory, what o2 sensors are you using where are they installed? Something is screwy with those readings. o2 sensor voltages should bounce back and forth between ~.2v and ~.7v. For ex., the last frame looks normal except for both sensors on bank 2, and the downstream on bank 1 all read a full volt. Downstream- I'm guessing maybe you gutted the cats or don't have the sensors installed? If it is a fueling issue, it is on bank one. You can get away with -24, but -33 is pegged. The m1 flash from B&G will come back with -20 to -25 fuel trims. I would check every thing I mentioned before.

Just so you know. With the exception of the downstream sensor voltages, frame 11 is abouthow everything should look.

 

I am using universal O2's at the moment. I'm looking at some Denso's they end up being about 57$ each I just need to figure out wich ones to get. There are like 40 differnt O2 sensors for an 01. The O2 sensors are located on the collectors of the headers and you are correct the rear O2 sensors are not even installed.

I went to my mechanic freind and talked about it. He thought that maybe it was the O-rings on the fuel injectors. So he started digging around and sprayed some brak cleaner on the intake. He said there was a change in the RPM but, I couldn't tell. He says this would mean that the intake gasket had a hole in it. This dosn't make sense to me. I mean it kinda fits the problem but on the other hand why would the turning the truck of and then on imedietly fix the problem everytime.

What would cause a fueling issue?

 

NTK's are the best for the money. A manifold/vacuum leak would help with a rich condition. O-rings would leak fuel out, not in.

Any of the things I mentioned before could cause over-fueling, i.e. too much pressure, injector(s) sticking open. Looking back over the freeze frame #'s, I don't understand why why one bank is in closed loop, and one in open loop at the same time. Then Again, like I said before, I have never really messed with cali emissions. Try posting that data up here:
http://www.bionicdodge.com/bionic/

with an explanation of the problem. Maybe Marty or Hemifever will chime in. They know these boxes inside and out, and will atleast be able to tell you if the fuel driver is acting right.

 

As far as the system being open on one side it may be that I need to tighten the botls on the headers yet again. I don't think they have quite finished their break in yet. Also it is the first time that I have noticed one opening and not the other. I'll go post on that site right now I think I still have an account there.

 

Ok I I finally found some O2 sensors that will fit my truck. I had to order them for a 2002 but, they fit perfectly. The plus side was that they are longer then the 01 to so they fit without splicing. All I can say is wow what a differnce. The headers made a big differnce but, having the right O2 sensors made a big differnce to. I haven't had the problem yet but, I've only started it once so I'll have to wait and see.
