Used my OBDLink MX+ for the first time yesterday. Very impressed. I downloaded the OBDLink app.
I got a call from my GF that her 2014 Jeep Grand Cherokee Limited was acting weird. I happened to be driving and started driving her way as she was headed home from work. She was nervous she wouldn’t make it and wanted me to drive it. “Great, so I can be the one stuck on the side of the road”, I asked?
It was missing at idle and hesitating under acceleration. Seemed like a misfire or perhaps a bad fuel filter? I mentioned it might have a code even though it didn’t have a check engine light yet. We made it back to the house, and I got to see her drive my truck, damn it looks so good with 20x12’s lol! What???? Not everyday you get to see your whip being driven down the road. Looks different than staring at it parked.
Anyway……she asked if I had something to read for codes and I was like for a Ford yeah …..then I was like wait actually I think I do have something. Opened up the OBDLink MX+ and I was excited to see what I could find. Man I am easy to please lol.
Found this pop up

Ok I had about 45 min before O’Reillys closed. They had one ignition coil in stock…..puurrrrrffect and might as well change the spark plug too. NGK of course…..yes I’m going to change them all now but at this time I just wanted one.
Found the firing order online and swapped out cylinder 1 coil and plug. 10 min. Took it for a drive, good to go! I couldn’t have been more proud of myself and so happy I bought that OBDLink MX+. I’ll let you guys wonder how I was rewarded later on.
Now to change them all and new oil change! Wrenching on my car has made me love working on anything.
