Throttle Response?

I seem to have an issue with my throttle response. When i step on the gas it takes a second or two to pick up. I just chaged cap, rotor, and oil, and i have a brand new K&N air filter. It doesnt rev up or anything, it just doesnt do anything for a second and then will start to pick up a little slower than i tend to remember. Any help?

Have you changed plugs, or fuel filter lately??? If not do those first and see if that helps. I always do the tune up things first before I get into the more expensive stuff.

ok, no prob with the plugs i got those and im getting some wires this week. However, i am finding it extremely difficult to change the spark plugs. Any tips from anyone on changing the plugs? Also is there anything i should know about changing the fuel filter or do i just unscrew it and replace it? And how do i go about checking my fuel pressure? sorry for all the questions, this is my first TPI car.

before you replace the fuel filter it's a good idea to relieve fuel pressure by disconnecting the fuel pump fuse and lettin the car run until it dies. then just loosen the lines. will probably still have some fuel in the lines.

to check fuel pressure you connect the gauge to the valve on the passenger side fuel rail. also might wanna relieve fuel pressure beforehand.

some plugs you'll have to get from the top, others from the bottom. when installing new ones put a little bit of anti seize on the threads.
