Jerking at 2000 rpm - 2008 Hyundai Getz 1.6

First off, is a check engine lite on,if so do you know the codes?It does have a cam sensor,the cam sensor malfunction gives a code reading,in general fuel probs do not give a code this is done bymanually checking fuel press ect....the module does give specific codes as well...I have seen a cam sensor give the prob. you list, BUT TEST BEFORE YOU BUY,you can get your own codes from the a.l.d.l connector,under dash...take a coated jumper wire and push one end into the g .circuit ,the other into the b terminal and watch the lite flashig in the dash,,ie, 2 flashes...pause then 4 flashes is an example....wilf

run fault codes and check for cam/crank position sensor/MAP/MAF sensors and accelerator position sensor.

Didn't notice which Jeep model/year you have but if it didn't have those issues before, make sure you don't put the filter on backwards.

How To Test The Fuel Pump 1990 2000 3 0L Ford Taurus
You are on the right track in replacing the fuel filter. Not enough fuel is getting to the engine. It could be a number of other things ... bad fuel pump or dirty injectors to name a couple. The link shows how to check fuel pressure ... which would tell you if the things like the pump are bad.
Might try some fuel additive injector cleaner to the gas tank to see if things improve ... relatively easy.
If it is the fuel pump or other fuel supply problems ... those are harder to fix

fuel filter,air filter,could be TPS sensor,crankshaft sensor.weak fuel pump.

This problem needs the diagnosis of the dealer to monitor the system in real time and watch what is causing this problem.

sounds like you got a clogged fuel filter and needs replaced will get worse

I would look for a fault in the ignition system such as a cracked spark plug. Might need a scope check to put your finger on the problem
