My 1989 civic will not rev past 3,250 after the multi-point swap it acts like its going into fuel cut (rev limiter) does any body have any suggestions

 

i did this swap a long time ago. i also had the same problem as you. Did you double check everything to make sure you had all the wires in the same spot? I found out that i mixed the 2 blue wires and the 2 white ones at the dizzy around .

 

how many check engine lights do you have.

If your light is on and you haven't checked it, don't reply with "It's on but I don't know what they are"

If it's not on, then it's harder to diagnose.

If it is on, find out what code(s) it's throwing and get back to us.

 

I do have a light on its for the IAT

 

You sure you have the right connector hooked the the IAT?

The IAT and EACV are interchangeable I think. (It's either that or IAT and TPS...I had mine mixed up when I converted to MPFI.) Meaning they'll both plug into each other...try swapping them and check for codes again.

 

Its the IAT and the IACV that can be switched.

 

I believe i have the right one plugged in the IAC valve connecter is green and the IAT connecter is white
