While driving home, the obd2 port fell onto my left foot. When I got home I examined it and found it was a power tap off of the actual obd2 port. I followed the wires from the fallen plug up into the dash and found a Spartan Industries 4G tracking device. I removed it. It might be a good idea...
When I start my car in the morning, I noticed the high idle goes down to 1K RPM after maybe 30 sec.
However, I noticed that once my oil temp reaches 87F my idle speed goes down further.
So I usually wait till that point before I pull away. It seems to make sense to do so, but am I wasting my time?
