VVl crazy idle issue
Im having some issues with my b13. My idle stays at 2500-3000 rpm if I disconnect the maf the idle drops down to a normal idle. Im using a de maf. I have a base ve flash on my ecu with the de maf. Its driving me nuts. The tps is set at .45 v and the throttle stop screw is set all the way out so that its fully closed. I dont know what else to try.

What ECU are you running?

stock b13 ecu with a nismotronic basic chip

Are you sure you don't have a vacuum leak at the intake manifold? Or around the throttle body to IM?

keep in mind if your using the VE TB it has a plunger thing on it that can be adjusted to bring the cold idle down.. but yeah it sounds like you might have a vac leak.

Bizarre that it still idles at all with the maf disconnected

Cold idle is fine. I'll check for vacuum leaks in a bit. If it idles ok with the maf unpluggled could it be that the maf is no good?

I'm sure if I went out and started up either the VE or the DE, then disconnected the MAF, it would stall.. at least after a few seconds. thats what makes me wonder. i have no idea

No vacuum leaks I used TB cleaner and sprayed around the manifold and no changes in rpm. So my car should not idle with maf unplugged?
