COP=Coil on plug

I found my book for my Innova 3120 and have been reading it. It does some freeze frame data. I still have to learn how to use the 3120. After I understand what I am looking at on the scanner and what I should be measuring, I will connect the 3120 and do a road test.

I watched several Youtube videos about WiFi Android dongles that plug into the data port(DLC). Several people like the ELM327 ~$14.00, the BAFX 34t5 ~$25, the OBDLink MX ~$90, and most of all the "BlueDriver for ~$100.

Does anyone have a favorite scanner under $200? I am leaning towards the "BlueDriver."

I did re-gap the spark plugs to .044 and it didn't change anything. I ordered 4 new spark plugs, the same as came with the car.
