sputtering sr

[quiksilvia]

ok some of u may remember about my sputtering issue, my redtop will cut in and out like a cylinder is missing or something only at full throttle and itll sometimes smoke at idle. i had my injectors tested today and they are all fine, and the turbo is still boosting normally so i think its something in the engine. im gonna clean my mafs and see if that helps for some reason, but does anyone have any ideas?

you need to pull your plugs and see if any one shows more buildup than others. I would not at all be supprised to hear that one of your coilpacks is weak/trying to die.
