I installed the kit today, did the battery disconnect as they stated. Not quite sure it was a full 2 hours, but I reconnected everything after I finished and started it up. It ran fine and after a few minutes stated idling erratically and threw a check engine light. The code was for the MAF. I disconnected the battery again and will wait 3 hours and try again. If that doesn’t work, I’ll replace the sensor. I guess those things are delicate, but I was careful with it. Also tightened up all the clamps just in case it’s a intake leak past the sensor.
