Need some suggestions on this.
Haven't done anything to my talon since last November, other than just driving it. Which is good i guess, but naturally the car has developt a couple issues.
One of them is it started to idle at about 12.5 afr but only after driving it for a while. The cruise afr is where it needs to be, so is both cold and warm idle is fine also.
I noticed that when the engine starts to heat soak, the idle gradually starts to drop from 15.3 down to 12.5. Than, as soon as i start to accelerate it goes back to 14.7~15.3.
Really seems like a software issue except it didn't do this before and either way i checked my ems settings and even tried to reload the file, didn't help. It seems that neither the engine temperature nor AIT has any effect on this.
Tried out a different wideband sensor today and still the same issue.
Any suggestions?
Thank you in advance
