hesitation

[wbsilver38]

more issues, lovely! when i start my yuk after its been off for a while, it idles a lil rough and when i get on the road it will hesitate when i first hit the gas. usually i let off until it warms up but the other day i kept my foot on it and it would rev real high then come back down and it did that like 2 or 3 times til i took my foot off it. i put new spark plugs in her and the fuel pump and filter were replaced about 6 months ago. i also put a bottle of sea foam in it and it only temporarily fixed it. i've asked around and did some reading here and from the sounds of it, it could be a number of things, idle air control valve, egr valve, coil pack, injectors, ect. anyone have any ideas or experiences?

k i'll try to get one tomorrow while the suns still out so it won't be blue, also i have not had a drop in fuel economy, its pretty much stayed the same since i got it, between 13 and 14mpg mostly in town driving and some highway driving, i got up to 18mgp on the highway when i went to colorado a few months ago

What plugs are those name and number. They look to be the wrong ones. Signs of blistering and deposits maybe from engine liquids or fuel additives.

not sure of brand, they were in there when i bought it, all it says on the plugs is AC 41-932 25321614. i have put fuel additives in it, lucas oil fuel treatment, o'reilly auto fuel treatment and octane booster. and if it helps, it hasn't kicked up any codes when it happens so far
