History of car,

-NGK Spark plugs with about 2000km on them
-OEM Coils & NGK Wires just installed

THE PROBLEM

When accelerating the car will have ignition breakup, this tends to be more frequent with half throttle apose to WOT. Car starts fine cold and hot, idles at 850-900 relatively fine

Videos..

Also, ESS has been cleaned and so has the MAF. I cant even drive the car with fear of something major happening. I am running a factory tune

What do the spark plugs look like?

What are the AFR's when the ignition is breaking up?
