Fixing low idle
Posted: Tue Dec 06, 2022 7:35 am
Hi,
I have a K20A2 with a PRA ECU and IACV delete (I got the car like this).
Recently I discovered an air leak at the intake, I fixed it but now I need to redo the calibration as it is too rich.
I got my idle at 14.70 but the engine bounces between 650-800rpm which is too low.
The easy solution would be to tighten the throttle cable but my understanding is that it could instead be done properly by advancing the ignition. I have no idea how much is reasonable though and I don't want to risk damaging anything. I haven't found any guides about this.
Could someone please help me out with this ?
Thanks.
