1997 honda civic d16y7 turbo idle problem
 

hey guys so I got my turbo in my 97 civic hatch with a d16y7 with a p28 ecu and i disconnected the iacv sensor. when I first started it the car started right up but as I let it run it started to sit around 1500 rpm and bounce between that and 1300 or so. just want the fix for it. once I get it going will get a tune on it probably a hondata but hope someone can help thanks guys!

Why not reconnect the IAC valve so the computer can control the idle?

because that's a 3 wire iacv and the p28 are a 2 wire so it can't run. the old 92-95 work but mine doesn't I've heard idle screws can work but i'm not sure.

I don't ever deal with mods like this..... I swear I thought I had read of someone figuring out how to use just 2 wires to run a 3 wire IAC valve....may have been a completely different application though.

A cold engine needs more air and fuel to idle at a given RPM than a hot engine, so if you eliminate the IAC then you either have to put up with super low idle and stalling when cold, or a high idle when warm.
You could crank the big air bypass screw in (assuming the TB has one) to make it idle decent RPM when warmed up, then you would have to use your gas pedal foot to keep it from stalling when the engine is cold.

I wonder if you could make an adapter to mount a different iac to your tb?
