Ok i have posted for help several times and still havnt gotten to the bottom of my problem. I have checked everything that the hesitation called to check for and still cant figure out wtf it is. i ran sea foam in the crank case intake on both sides and in the fuel tank. it burned off in the intake but does it change the way it runs when in the fuel or n the crank case??? also should i check my plugs for fouling again now that i have ran them? and why are my ssqv bov opening at vacuum? i took apart the bov and put spacers in them to keep them from opening but they still do. zero vacuum leaks and brand new wiring harness, just replaced the MAS sensor still acting stupid wont rev idols perfect. some one please help.
