just change spark plugs in my redtop sr20det. one year past since last sparkplug change . i use the OEM platinums pfr-7b-11 NGKS. i installed the new sparkplugs in at .034 gap. Since the new sparkplugs my cars been getting a blowback at every shift no matter high or low boost. and the car feels very sluggish at mid to high rpms. it sounds loud but goes nowhere like hondas

. You guys recommend increasing or decreasing the sparkplug gap in this kind of situations?? the sparkplug gap should be the problem to this.
its moslty stock with exahaust.
i tryed seaching it but couldnt find a answer to this one.
thank.
