sounds like it may be the TPS throttle positioning sensor Just a guess, but an educated guess from the info you gave. This sensor is responsible for setting the idle during warm up. It sounds like the TPS is tricked into thinking the car is all warmed up, and not giving the motor enough fuel. I hope this was helpful. Cheers from Nova Scotia!
I can't imagine anything being affected by changing the oil other than the valves in the heads. I assume you have good oil pressure hot or cold. I suppose you could be moving a wiring harness around when you take the oil filter off. It would depend on if the rough running is mechanical or fuel or ignition related to say what to check first. I would have to figure out which area is affected first. Something like a sensor or a dead miss on one cylinder could turn the check engine light on, but most fuel and mechanical issues will not do it on a car of that year. If one of the coils was failing when the engine is hot, changing the oil should have no effect.
