Is the check engine light on?

Have you checked the ignition timing?

I would get the compression tested and if that is in spec, I'd remove the catalytic converter and see what condition it looks like inside. The cat can get clogged and your engine will run like you describe.

Is this a recent problem? or a new car?
I would check your ignition timing, and your cam timing, when I had my timing belt install wrong (one notch out of place) it was really slugish.
your cylender compression should be 195psi, 13.44 Bar, and not more then 20psi or just over one bar variation from cylender to cylender.
Also, when you changed your spark plugs how did the old ones look? if you take one to a mecanic, or auto parts store they should be able to tell you if you are running trying to burn to much gas.

have your timing dubble checked, there is a set of arrows on the head that the cam gear lines up with when the crank shaft mark is lined up with the pointer, after you have that done, have them check it with the timing light as well for ignition timing.

Yeah, take the cap off the distributor and take a look at it, and also look at the rotor...replace if there is a problem.
