Need you guys' opinion.
Well I just bought my car about a month ago, so I don't know much on maintenance history. It's a 93 3.4. The car is hesitating and I don't know how to describe it. The best word I can come up with is "stumbling". When I lightly press the gas it stumbles.. Do you guys know what this might be?

I guess I should have put what I've already done. I changed the oil, and ran some Lucas injector cleaner through it.

The fuel filter is clamped to the inside of the unibody frame rail on the left side, just ahead of the rear axle. So I guess it is hard to get to. Unless you have the car on ramps or a lift.
You'll need flare wrenches to undo the forward connection. And I'd avoid a Fram fuel filter. I bought one for mine and found it has a smaller diameter than the original so the filter isn't held tight in the bracket.
As for your car's hesitation problem, I'd check the throttle position (TP) sensor. That component tells the computer when the throttle is at idle, when it's depressed, how far it's depressed, and how quickly the position is changing.
Using a scan tool to check the sensor is ideal but you can do it with a simple voltmeter too. Do you have a voltmeter. An old analog style is best for this test.

I just changed the plugs and the wires guys, and it seems to have fixed it. Ill take 1aug's advice and change the fuel filter as well.
Is there anything else you guys think I should do to it? Seeing as I just got it?

Well since winter is around the corner, you could do a coolant flush and put antifreeze in there. That wont do a lot for how it runs but you're gonna need antifreeze in there anyways. Might as well do it now lol
