Hi all,

 

 

 

After swapping out the stereo in a 2007 Camry I have noticed that the car is idling at a very low RPM at intersections/lights etc. Any ideas what might be causing this?

 

I did my research online and found many references to swaping out the stereo to be a fairly straightforward process and nobody reporting any problems. To simplify the process I used off the shelf parts and no soldering etc (Metra 99-8218 Dash Kit + Sony XAV-V631BT + Aeropro wiring harnesses), thus far everything works as expected (radio, AC, steering wheel controls). The only drama is the low idle, to the extent it sits at about 500rpm and feels like its going to stall.

 

My initial thoughts are it might be something to do with the Shift Lock button, as to install the radio I had to remove the center console and plastic around the gear lever. I'll remove these parts today but am not certain its the problem as the car didn't appear to have any problem changing gears driving around town etc.

 

Any ideas?

 

Thanks

I'm guessing that you looked on YouTube on how to 'How to replace a car stereo', and a lot of the time they [YouTubers] suggest to disconnect the battery as part of the best practices. However this can cause the ECU (Engine Control Unit) to wipe its auto configuration for air and flue mix. The car's ECU auto configure it air and flue mix over time and consultancy calibrating it's fuel mix. I had very similar problem and I found the solution was to let the car idle for 30 minutes not letting the RPM to drop to much before staling. Overtime you will find that the car will sorts it self out.

Presumably you disconnected the battery when you replaced the stereo. If so the ECU has to relearn the settings for the ISCV (idle speed control valve or 'stepper' motor depending on which system is employed on that particular vehicle). It's best if when the battery is reconnected after such a situation you immediately take them for a small drive of stop-start driving and cycle the various loads like A/C and headlights so it can do so. Until it re-learns the particular settings for different situations it'll just be running baseline which usually results in low idle and sometimes even stalling when coming back to idle.
