Default Still having bogging problem

Im still having a problem with my car bogging out. So far i've changed plugs wires fuel filter. the car runs fine when im not all the way down on the throttle. I took all the wires off made sure the plugs were properly tighten and also i checked each wire to make sure i heard "click" when re installing them so i don't think its that. Also i cleaned my k&N air filter and seafoamed threw the break booster line. What else should i check?

Fuel pressure. Should be in the 38 to 40 range at idle or around 42 to 45 PSI With vac line disconnected. Make sure there are no vac lines broken or disconnected. Leaning on the passenger side trying to get at that 8th plug you can break vac lines at a couple of points along the intake or even the the one over by the PCM.
