series 1 engine from a celsior going into a series 1 ls400. i replaced a coil and it is idling finally.
i have codes 47 and 56. the sub tps sensor sends the right voltages to the ecu, 0v at closed and 5 at open, but the butterfly is always open so the sensor is reading as open when it should be closed? i think the sub tps could be messing up as a result of the code 56 trac problem? the trac motor goes back and forth when the key is turned on but could be stuffed?
car idles but any sign of throttle it will die. going very slowly on throttle it will get to maybe 2500 but then tries to go back to idle.
any suggestions welcome.
