2008 Honda Pilot check engine/VTM-4, Resolution in Description

Had this issue pop up with my pilot took a video to share and see if anyone can point me in the right direction. Few days ago changed the engine oil, transmission fluid and vtm-4 fluid. Upon change the fluid I started the car to warm up and check the tranny level as per the manual and noticed right away the car was running strange maybe a misfire and the exhaust smelt different but it went away after a minute or so. Only thing I could think of was that I used a full synthetic oil for the first time. Flash to today leaving work and the car starts bogging down and I get a flashing check engine like and should vtm-4 light come on, runs normal untiI I stop and go then it&sluggish. here is a video of the lights coming on about when the car starts to warm up. Tomorrow I&going to have a better look and read any codes, from what Ive read I should check the plugs which were changed by me at 100k I&now at 138k, as well as check the EGR ports and pcm valve. FIXED: indeed leaking oil into the spark plug tube which that plug was loose so oil getting into combustion chamber. changed all seals and gaskets with new oil and its running perfect again. here is a link to some pictures and process.
