Engine Performance Issues, Ticking Sounds..

Oil was recently changed, and car passed massachusetts' emission test with good results.

However, when accelerating from a stop or lower rpms with more than a quarter throttle, the engine sputters, jerks, and comes close to stalling.

This problem has been present since I got the car a month or so ago, it runs fine otherwise. As soon as i got it i changed the old autolite platinum plugs and replaced them with AC-Delco's. Slightly better, but the problem is getting slowly worse. Could this be a clogged fuel filter?

Also, there is a ticking noise coming from the engine under all operating conditions, you can feel it through the front three injectors. Its not a metallice knock, just a ticking thats constant. Click-click-click. It increases with revs, but will eventually be drowned out if your revving high enough.

Im planning to change the fuel filter, but are there any other possibilities or something i may have overlooked?

Look at the fuel pressure when this occurs this require hooking up a suitable gage with a long hose and taping it to the w/s ,drive it and see what the press. is during the event, post back results. BTW, very good job on car info and description of problem, rare in these forums.
