Bad ECU? Idle Related
So, I have been having trouble setting my idle, I already have read a bunch of threads about idle troubleshooting, here and in the non dash forum, and still can't figure out what's my problem.
For almost a year my idle has been at 1000 rpm, I know that it's not very high, but what's driving me nuts is the fact that it can't be set lower, I even bought a consult cable just to enter to the timing mode for sure, while in timing mode I can adjust my Idle as low as I want, I am able even to stall the car by decelerating it with the idle screw, but once I exit timing mode, the idle returns to 1000 rpm.
When I first bought the car It had some idle and bogging issues, but cleaning the IACV and servicing the ARV was enough to let my classic performing like a brand new car, and of course I was able to set the idle even without the consult cable, via the old rain dance without problems.
Now, since in timing mode I'm able to decrease idle as I want, I discard vacuum leaks, also, during normal operation, I can see via the consult cable the the IACV is operating at 40%, so for a weird reason, the ecu insists in maintaining the 1000rpm idle. Could the ECU be fried? Have any of you have a similar experience? Any ideas for making the ECU learn what idle speed I want by another method?
Aditional details:
sr20de Highport, Mexican version sentra se-r aka Tsuru 2000GSR, I/E/H
Any input would be appreciated
