Erratic Idle

what are possible causes for an erratic idle?

here are my symptoms

vacuum reading is fine its about -14lbs

but the idle goes from 1000-2000 rpm

and the AF all over the place of course

the ignition goes from 0-6 values

I dont have any vacuum leaks
i checked the IAC valve and it seemed ok

what possible things could cause this or is it just tuning?

Try cleaning the IAC valve.Or adjust the slider in the idle tab of Kpro.

Ok I think I found the problem

car is idling in columns 6-7

it should be 1-3 no?

does this mean its a vacuum leak for sure?

That is a vacuum leak.

Ok - once the posts get abusive I have to moderate them, so your last two posts have been deleted. Also consider that the best way to get us to help you is not to post 'fuck hondata' on public forums. While we're sorry to hear that your ECU was damaged, it is out of our control and we cannot replace every ECU that has been damaged in a customers car. There is nothing in the KPro which can electrically damaged the ECU, even if something went wrong with the KPro. We would like to keep working towards a solution for you, but it up to you.

How about a solution to this guys problem? I've tried three different 3bar MAP sensors to no avail. They all check out with a voltmeter with the key on but, once you go to start up the vehicle it goes to 0.5psi columnand of course the idle is very erratic

The problem was sorted out - the injector driver IC in the ECU was damaged from either the injector or injector wiring.
