3400 swap

[cwahl]

Hello folks

I have completed a 3400 and grand am gt tranny swap into my 1999 malibu.

This is fine only I am receiving the following error codes. Can anyone tell me what they mean or what it could be?

To complete the swap I used the 05 sensor and the 99 PCM, 99 BCM and 99 wiring harness. I have been using Xonelith's stock file to get my car around town. Any help would be greatly appreciated.

I was an idiot and did not back up my 99 malibu's os file and instead did a complete reflash of xonelith's 2001 OS over it.

Currently LTB1% is sparatic. Could this be caused by the cam throwing my MAF off?

I'm not sure about the swap, however, there are great sites out there for determining the codes. A few are:

As for the LTFT, definitely the cam or a combination of your mods. You'll need to do a bit of tuning to get that right. Have you upgraded the injectors or are they stock?

[cwahl]

they are the stock injectors.

i am running a very close setup to yours xonelith.

my maf is currently running close to a 9lbs more air in it per minute. I will post a log of this when i run filtering out PE.
