wont start
Hello guys, im new to the honda world, so i just picked up a decent 97 civic coupe, d16y7, 5spd, i love the car, great on gas, normal mods, exhaust, coil overs, intake, header.. now when i drive the car it runs great, fires right up but it acts like when the car is warm it wont fire, juat turns over an over, i checked if i was getting spark and i am.. now i have read that the efi relay or main relay would cause my symptoms... like i said im new to the honda world, om used to carbed v8s so take it easy on me lol... thanks in advance for any help guys an gals

trouble codes
So i did the code trick of jumping a wire on the test port, i got
I got 6-22-41-65-91, now 1 i thinks for the ect sensor the other 2 are for o2 sensors but whats with the vtec codes an the gas fuel tank pressure sensor?? Car is a 97 cici coupe, d16y7 no vtec... could ot juat be the pcm they used??

new ecu but small problem
so i swapped out the p2p that the last owner had in the car, now my motor is a D16y7 so i picked up a p2e which the car should of had in the first place. car runs but idles low like a hair up from 0 so say 2-400 rpm an its not surging its smooth.. does the new ecu need to learn the new fuel curves? like do i need to reset the ecu

Re: new ecu but small problem
i pulled the codes, 14,41,65.. iirc 2 are for the o2 sensors the other is for my iac valve?? i disnt have that code running the p2p ecu... also im running a y8 intake manifold, would it be because im running the y8 throttle body still??? bought the car this way so its all new to me

Re: new ecu but small problem
<p>An autotragic ECU won't work. You'll throw CEL codes for the TCU. Unfortunately, you also have a Y8 intake manifold, which means you'll have issues with getting a functioning IACV, which is probably why the idiot PO used an EX ECU.</p><p>You need to get a Y7 throttle body with IACV, reverse the throttle plate, block off the IACV port on the back of the Y8 intake manifold, and that should help resolve your next step. Still, though, you need to resolve the issue of having the wrong ECU. Hopefully the PO didn't also **** your wiring harness to hell and back.</p>

Re: new ecu but small problem
Yes I still have the one we spoke about before but this is the tech forum so it's bad practice to be talking about buying and selling parts in here. That said, you should still have the pms we exchanged saved in your inbox if you still need one.
Now, about the technical aspect of your problem. If you didn't have an iacv code with the P2P ECU the previous owner must have done the wiring conversion for a two wire iacv. So in order to use the y7 iacv you'll have to reverse the wiring mod at the plug and the ECU. Hopefully for your sake the previous owner just depinned the extra wire (orange) and left it dangling but there's a good chance it was just cut and you'll have to extend from the cut sections to the pins or replace the wire entirely. I would suggest you take a look at the iacv plug and the ecu wiring and see if you can locate both ends of the orange wire.
