    Air in fuel symptoms??

    I've been trying to get my truck running right for about a year now. The only thing that hasn't been replaced is the wiring harness. Everything else is new. Built motor, trans, fuel fuelers, twins, nicktane filter setup, raptor 150 lift pump, exergy 60 overs. The truck rattles in all tunes from...

    So here's an update: it's injectors again. The first set was a remanned with 60% over tips (found out when I sent them back they were actually only 50%). One was hung so bad the fuel knock sounded like someone was hitting the block with a hammer. So to hurry the replacement along, I sent in my...

    Quick update: So all the issues I was having with the AC, oil pressure, and low coolant were all related to the OS. Changed it to the 6006 and everything worked again. Haven't had a chance to drive it yet so I'm not sure about the miss. Ill drive it and log it and post what we find.

    I'm hoping the 6006 will fix it but I'm open to a newer os if I can get it programmed to get the ac working again... 102-106 here the last couple days.

    The wiring for an 03 is different and the os for 03 and up needs the right wiring to work on some of the sensors. The codes i'm getting aren't listed for the 02 but they showed up in the 03 list. I checked the Efi live site when my mechanic told me it was the os and the tuners on the Efi live...

    Well I think we found the problem.... The 02 os uses continuity based sensors, 03 os uses 5 volt reference sensors. The codes we got are 03 codes... I think my os for my Efi live tuning was sent with an 03 os. We are loading the stock 02 os in the morning and I'll bet my ac works and the...

    BFG - you can actually feel the miss during acceleration and then even just maintaining speed. The sound I hear in the exhaust and engine compartment matches the kind of almost chatter in acceleration and It changes with RPM. Trust me, I've been hoping it was just something simple or stupid on...

    I'm just about to the point of setting this truck on fire and walking away.... I started this build last summer (found a spare motor and sent it off to get built), got the motor back in April, put it in in May and have been chasing problems ever since... I just want to drive this thing and be...

    I really appreciate the responses. I bought all new sensors for the AC just to make sure I wasn't chasing a part problem. My first order of business will be to fix that problem today. i thought the same thing anout pinched wires during installation. ill update progress later today and ill...

I had injector issues to start off with but I believe I got those handled...
