LQ9 2004 TAC troubles I am turning a LQ9, out of a 2004 Escalade, into a turn key engine.
I am using same wiring harness but simplified and a Nelson Perf´s tunned ECU.
Engine starts, but do not accelerate.
When power, the Throttle Actuator make the regular noise when sligthly moves the butterfly, but when depress the pedal, it remains the same.
Engine did not came with the TAC, so I bought the 25173339 TAC. Was just plug it in.
After scan it, following codes was read.
TAC in powered, is grounded and battery is charged, so, any idea????
