C3 Drive by Wire Help
Pllease help, I’m scratching my head to the bone, I know most guys wouldn’t convert their C3 throttles to drive by wire & I screwed up by doing so.... My Hp Tuner fault code P2127 & 2138 freeze frames. Should the accelerator position D & E match? I keep losing my drive by wire pedal, it just idles once the fault code pops on my 68 with LSX 454 crate engine & GM control system.

you need to find a GM service manual for the eng you put in
but the Silverado pedals,have 2 rheostats,1 goes from 0-100,the 2nd one goes from 100-0,,a service manual will tell you
1.wiring
2.a trouble tree [for diagnoses]
3.a dtc code break-down
