Can anyone tell me what this code means and where is the part located in order to replace it?
The car will stall out now and then when I come to a stop and has been rough when starting it up.
It also had a few other codes but some may be older codes that have been fixed.
The po725 said Trans Engine speed sensor
Also had a po171 System to lean, P3631 and a P0011 Intake cam over advanced.

Thanks
