okay, here is my issue

i have a 00 y8 motor, it was swapped into my dx hatch.

the head had some crazy tapping issues so i swapped a y7 onto it. with a y8 manifold that was previously on my d16y7 motor. so it wont have any problems. except on the back there are 2 holes with 2 bolts it plugged it because i believe the y8 manifold i had was from a manual and not an auto. because the auto has them blocked off.


here is the problem. when i run the y8 ecu it will start the car but it idles all [freak]ed up...


when i swapped the y7 in there, without doing the iacv fix it wont start. it sounds like it wants to but wont. then i get an error code 14 [ics malfuntction??]

also when i had the y7 head on the y8 block still running the vtec cpu it would idle all [freak]ed up and be around like 100rpms lol.


all i did was change the oil, headgasket, and coolant. I dont understand what is going on. Can anyone help me? i had an old thread but i felt i needed to update, because its no longer how it was.


for reference here

HELP

 

Is your car a manual?
Are you using a y8 manual ECU?

An auto y8 motor uses a 3 wire IACV that is mounted to the throttle body and a Y8 manual uses a 2 wire IACV which is located on the back of the manifold. Sounds like you have them mixed up.

 

my car is a manual

im using the manual ecu

i dont have them mixed up...i put the y8 intake manifold on the Y7

just think of my motor being a y7 and thatll clear up any confusion
