    guys,
    on my 1990 k1500 4x4 with 5.7 v-8, what is the part thats on the same bracket as the EGR vacuum solenoid and electronic spark control module ?
    its at the rear of the bracket on the passengers side, and has a green electrical connector and vacuum hose that goes to the back of the throttle body.

    i have replaced everything except that part and the spark control module. including, EGR, EGR vacuum solenoid, TPS, IAC valve, knock sensor....
    while im at it i want to change that part, if i knew what it's called.

    thanks
