No it was going on before this as well, though it got a bit worse after i did the tune-up. Seemed to be ok for a bit and then went back to acting up. This car went 2 years with absolutely no matienence besides a changed oil filter that wasnt even on snug enough (i didnt even have to try to get it off with my hand, it jiggled like someone turned it twice and left it). Caused a horrendous oil leak from it. Correct me if necessary here, but i know people who don't do matinence and ive heard that after putting new parts on, the car tends to perform better but break other older or broken parts due to the boost in performance. I dont know if that's true but i chalked it up to that and continued to try and fix each and every problem which now has got me here. Before this i replace the Camshaft Position Sensor (last code i got before now), and it made a big difference. The car actually slowly broke down without it. I dont know if thats normal or if that part controls something necessary for that car to run but ill say this, it was broken the car wouldn't start. I replaced it and had less problems but basically had the performance it does now.

Secondly i found the firing order from a diagram online found here:

Imagine your facing the front of my vehicle, spark plugs are in front and then also in back. This shows a side profile so i just turned it to the way i see my engine and plugged the wires according into the distributor. I verified this is correct, as i didnt know it at the time, the firing order is on the distributor cap. It felt a alot better than before and it looked like 4-6 were wrong. Roughly here is what i remember it looking like, wires leading to the distributor were ok but not put into the cap correctly like this, starting from bottom of the distributor on the diagram : 456 132.

And we double checked because it started acting up a day or two after, we had the same conclusion as you: Maybe there loose or gaped wrong. All was in the correct place though, the wires tight and the spark plugs also in tight. I will double check tomorrow but im sure its fine.
