View Full Version : How to fix SR's high idle

according to the FSM it says the steering pressure switch and AC switch should have voltage at the ECM pins, on my harness the wires are cut off so the ECM always sees 0V. So is that why the idle is high?
I have a S13 SR but I'm reading the S14 FSM, is it the same results?

Is there like a negative 4-5V source I can splice into

So would giving the ECM the voltage be right thing to do?
Anybody else done this

I just lowered my idle today, turned the IACV screw a few times, brought my idle down from 1200-1300 to 800-900

I think you are going about fixing the idle the wrong way, just how high is your idle? Positive of no air leaks? (at manifold)
I am not using my power steering pressure switch or ac The voltage reference is to bump up the idle speed when making low speed tight turns ie a parking lot, if the pressure sensor is disconnected idle should not be high b/c of it being disconnected, if anything the idle should drop when making low speed tight turns with the sensor disconnected

there is no leaks, screw is tigthened all the way, and idle is about 1300.
But when I use the consult blazt, I can set the idle to around 800 The software tells the ECM to adjust the IACV, and if you think about the PS and AC as one of them is in use the ECM adjusts IACV.
All I'm asking for is if someone has done it or can probe their ECM S13 SR, to say thats what they are reading
If I give the ECM the wrong voltage it will fry
