Default d16y5 turbo - misses

i just got back my car from the shop it seems to run fine except that it misses every now and then, like a sudden and brief (split second) power loss.. what would this be? and how to fix it?
open to suggestions!

The plugs might be gapped bit too much causing the spark to blow out during boost.

I had the gap set to .035 running 15 lbs of boost and it was cool

Does it do this under part throttle?? The Hx is a lean burn engine ya know...and all of the turbo parts you added may cause it to hiccup now....

i gapped new ngk v power spark plugs to .44 which is the stock setting.. should i reduce the gap like urs? to .35?

"hickup" best one word description..

i have an a/f auto meter gauge, also my turbo timer reads and display o2 signl in volts. this reading is allways too high, like 2 volts + when it supposed to be under 1v.

hx primary o2 sensor has 5 wires

A hic-cup would be caused be lack of spark. Detonation would be a lean burn condition. Yep, smaller gap needed

yup, ignition is stock.. will try 35 first then go down if needed.

edit.. using blue box and wallbro 255 pump, fuel shouldnt be a problem

the crossover from the economy mode in the d16y5 is a really noticeable jump and when im cruising at about 75 in 5th it is hovering around that crossover. It may miss once in a while

Pretty Sure the HX uses a 5 wire wideband o2 sensor...which operates off different voltage threshold than a standard o2 somewhere around 1-3 volts i think.
