I have a sick MP3 250 and was trying to rig up some software to connect to my ECU and read the CEL code(s).
I canít seem to find the ODB plug. I found pictures that looked like it was near the edge under the seat access port.
Symptoms I am dealing with:
It ran fine all summer but when the temperatures dropped it wonít start/idle. I think winter killed the battery so I could use suggestions there as well.
My plan is to clean the throttle body, use some sea foam and swap the battery out. Then see what the ECU is telling me and go from there.
I am a new MP3 mechanic but I have tools etc from maintaining and working on cars much of my life.
