i already did that and they couldnt get any reading neither could autozone. i did it again at both places two days later and it was the same no reading. i also used a jumper to cross the grd with the ten on the diagnostic port and it also gave no message. the check engine light is on though and the o/d light flashes constantly. i'm goign to replace the throttle position sensor and the turbine speed sensor now. i already did that and they couldnt get any reading neither could autozone. i did it again at both places two days later and it was the same no reading. i also used a jumper to cross the grd with the ten on the diagnostic port and it also gave no message. the check engine light is on though and the o/d light flashes constantly. i'm goign to replace the throttle position sensor and the turbine speed sensor now.
