I got a Bluetooth OBDII reader and cleared the existing codes and the check engine light.
I let it collect data while idling, and there was nothing. It wasn't missing. A tiny surge was all I could feel. This is coming off a week of temps in the teens and lows about 0. Yesterday was upper 40s
I drove it for about 30 minutes on the interstate (65-70mph) and surface roads (35-55mph) with some small hills. The reader was on and recording. There were no faults. I don't know how to read the data, so I don't know if the readings were high or low or right on.
I could feel a little surging/lagging on the hills, but again, no faults were detected.
After I let it sit for several hours doig some work on it. I started it back up, and it started to miss again. I didn't have the reader on at that time. The check engine light did not come on
I'm to go hook it back up shortly
