When I put the TAC motor on i noticed the butterflies were slamming shut and sticking shut. You would have to really stab it by finger to get it to open up. So probably the wrong thing to do I turned the adjuster screw a little until the butterflies would quit sticking. Now I can not get the TAC out of FMEM forced Idle. I adjusted the screw back out, have double checked my spring placement. and nothing works. Replaced the EGR valve also and am getting a Low circuit reading on that as well P0405. Any suggestions?
-
Try disconnecting the car battery for about 30 minutes to reset the system and drive a few miles for the idle to reset.
Did you disconnect the TAC when you were moving the butterflies? with the TAC connected, the TAC could act as a generator when moving the butterflies and damage other components like the PCM.
-
yes i did, after further examination the butterfly was open about 20 degrees or better even at idle. I tightened the spring in the TAC one full turn. Fixed all
