Car feels weak,Plugs?

[RaysTsi]

Ever since I got a tune-up at Precision Tune auto(they did my Timeing Belt) My car just doesn't feel as responsive. I had them put in NGKs. How can I check the gap on them.

Be specific as I have never changed or removed plugs before and I :dunno: how.

You'll need a spark plug socket and a gap tool, Take the plug wire cover off, and twist off the covers for the wires, and pull them off. (remember which goes where!!) Thake your socket, and take them out, then check with your gap tool. correct gap is .28 i believe.
