You could have some water in your gas, try putting some seafoam or HEET in your tank and get some of the highest octane rating you can get and put about half in the tank and see how that does.

P0132-(P0132 HO2S Circuit High Voltage Bank 1 Sensor 1)did you wire the 02 sensors back in right and how did you extend the rear 02's if you cut and crimped you should have soldered (sp?) them and heat shrinked the lines this is an electrical issue

 

Man i have been through 50 tanks since this started a year ago i just cant fix it

 

Okay lets start small:

1.When is the last time you changed your spark plugs
2.When is the last time you cleaned your throttle body and PCV vavle (or replaced)

 

#1 last week
#2 never and i only have 30,000 miles should i have done this already?

 

Couldn't hurt. I get the P0300 code sometimes and was told It was due to the lopy cam I have BUT.... I also have some oil burning problems and believe that may be some of the cause as well. And yes I have a catch can.

 

keith have you had a dyno done with an A/F chart?.....maybe running too lean?..

 

I know it is lean but how do i fix it?

 

I am not current on modding the Ram 5.7 but contact one of the vendors here like HHP or PPP...these guys are pros on getting the Hemis tuned....and if you know you are running lean you better act before you have to replace the engine in that badazz lookin truck of yours..

 

Another thought keith...have you tried replacing the O2 sensors?....I had a similiar but opposite problem...truck was running extermely rich...turns out one of the sensors were bad...

 

The P0300 code reflects that an "Engine Misfire Was Detected".

I had a similar issue with the Version 17 tune on the predator (I simply switched to version 18 and the problem went away, however).

He doesnt have the predator tune Momo...his is a Ram 5.7 hemi....with some slight differences from the LX 5.7s..

 

To help with your lean issue all I can suggest is bumping up to the 6.1 injectors and monitoring a wideband A/F so see if that helps any

 

Yeah im going to talk with B&G tomorrow and see what they can do for me. right now the only tune is Superchips and they say not to use it with long tube headers. there is another hand held tuner but i cant remember.also im wanting the prediter to come out for the trucks to se what it can do.

 

I really have a hard time believing your running lean with just longtube hedders and superchips. How or who told you that you were running lean. I had a 6.1 cam, Pacesetter Longtube Hedders, Ported and Polished Heads and Superchips, Nitrous, and never ran lean on my 5.7 Hemi truck. I ran an Innovate Wideband A/F and always monitored it and never ran lean

 

No no superchips just long tube headers thats it! the dealer told me it was lean and i dont know if i can belive them. this is what it does when it's cold and worm somethines it bogs down and backfires
