With the engine at idle pull the vacuum line off of the fuel pressure regulator port.If gas comes out it is shot.The engine jerking could be spark tracking to ground at the plug wires. Spark plug grease on the inside of the plug cap should solve the problem.

If you suspect a bad fuel pressure regulator,you can hook up a fuel pressure tester to the rail or you can take it to a garage that has the equipment to test it.You should have changed the fuel filter already and made sure everything else is good IE plugs ,wires,air cleaner ect.

It would seem odd that you would equate a fuel pressure reg. to the word periodically, sounds more like a heavy misfire, or your torque converter hunting in and out of overdrive/lockup.

i own a shop,an any car will run bad if its not got the right amount of pressure on it,it will herniate and back fire,also stall out on hills,be hard to start,and often die once it has been started ,it will make you think you have about 20 things wrong with it,when its really just one thing,but it makes them run really sick,good luck,i hope this help,s.
