i just did the mpfi swap with pm6 with premade engine harness. the car idles at 4,000!
but when i unplugged the iacv, it has a surged idle from 1000 to 1500(not exact)

when unplugged i get code 14 and nothing else. when plugged in, there are no error codes.

any help?

its not. i checked the gaskets between the block and mani, and the mani to tb. they are good and tight. the coolent lines have now been bled out, its running a little better but still at high idle, around 2,000 with very little surge[+/- 50-100rpm]. (thats without the iacv connected). when i do have it connected it goes to a steady 4,500rpm still. what is happening!?!
