Default D16Y7 Coupe with idle problem :(

Hello Honda Tech users

Coupe D16Y7 97r Euro Version

I've got problem with b7 manifold
It's the same as D16Z6
http://civic-eg.com/pics/diy/d_im_co...n/DSC_0299.jpg

My changes
intake manifold d15b7
throttle body Z6 or Original TB Y7 with IACV not blocked
IACV from crx ZC DOHC obd0 now IACV OBD1 from Civic 1.5
obd2a to obd1 jumper harness
chipped p06 with d16y7 basemap - original ECU P2E
Original engine harness obd2a

and I do this

https://honda-tech.com/attachments/t...8ekwiring2.jpg

My question is .. If I change it to obd1 that is all I have to do ?? Because my problem is with idle. Only stay at 1500 rpm , maybe this is problem (link below)
Honda PP4 PM7 Electronic Idle Air Control Valve

and I should use it ?
Honda P08 P0A P0B P0C P0D P0E P28 P2J Idle Air Control Valve

Or someone have a good basemap for d16y7 on b7/z6/y8 intake and throttle.

Please help

Did you leave the Y7 IACV on the TB, or did you put in a blockoff plate?

What car, wire harnesses, and specific OBD1 ECU? Add this key information or this thread is locked.

yes still bolted , not blockoff plate - this is problem ? It seems to me that the engine works in suction all time - this is possible ?

Maybe this is it.. incorrect connected cooling system

You need to block off the iacv on the throttlebody, its not need it.

edit: You'll also need to use the chipped obd1 ecu because I believe the p2e ecu looks for the 3 wire iacv.

The Z6 TB has a FITV that might also be causing your problem. Remove the IACV or FITV from which ever TB you want to use, and make a block-off plate.
