. Make sure to spray very very little at a time incase you have a leak. If you have one, engine will stumble a little once you hit it with the water. DO NOT OVER SPRAY...keep it short and sparatic.

I am having somewhat of the same problem right now, Bank 1 is lean... I'm not boosted but bank 1 is running lean after I changed out the o2's w/ the Bosch ones. Took it up to my tuner and he logged it and then we swapped 'em and bank 2 is still perfect but bank 1 got better (it was showing +25 and now its at +8 on the LTFT's). So we adjusted the tune a little and I was on the way back home and then the truck started bucking and running real rough when on the gas. Logged it and the bank 1 sensor was showing 45mV and not switching at all so I disconnected it to make it to the house. Can't figure this **** out. I guess I'll do more trouble shooting tomorrow...Zed

Storm, did you find the problem???
The other day I changed the O2 sensors on the drivers side. It started running a little better. The more I got into the throttle, the better it ran. Till last night... I was driving home and it started running like ****! There was a point where I couldn't get over 45mph! It was bucking and wanting to die. I made it home. This morning, when I started the truck, there was a little bit of blue smoke at 1st! WTF??? It cleared up within a sec or 2. But the truck was idleing like
I ended up parking it, and driving my room mate's Dodge 5.? non Hemi in to work
What is the world coming to???
When it was running better but still surging, I would hear a lot of air pressure release then the truck would surge forward. Does anyone know what that would be?
I think it's clogged cats but I don't want to fork out the money for new cats just to find out that that's not the problem. I beat on them with my fist but I didn't hear any rattling...

I forgot to mention... Last night I had a Bank 2 low voltage code, MAF code and a repeating EGR code. I didn't even think to write down the P numbers. Also, the right bank long and short term fuel trims were in the negative. What in the hell is going on???
