    Ok so 1991 hackback dx dpfi to mpfi

    what do the three lines on the mpfi go to . We are having problems getting it to run it will idle all day but I think we need the lines that go to it. The one I know goes to .


    its like this

    you look at the mpfi setup there are three line inputs the left on and middle are not hooked up the one on the right is hooked up.

    Do I need them I know the one on the right i shouldnt since the throttle body does not have the sensor for it . All the parts came off running 89 crx
