i recently just tune my car a 1 week or so. just today i gunn it a couple of time and it bog out on me (anywhere from 2800rpm to 3500) after that it will drive or if doesnt pick up between those rpm when i step on gas i would hear my intake suck in air but it doesnt go anywhere..mph would just drop..i would have to take it out of gear put in a lower gear and punch on it than it will pick..

i checked, battery +/- make sure its tight,all sensor, vacum line/ ground wires, ngk plugs make sure both ways are tight. even replace spark plug.

the car feels like it want to go but something is holding it back..
the car crank up fine/idel where is suppose to be
