Hestation problem. Changed fuel filter ran ejector n it.cleaned mass air flow.no code or check engine light on. Any help

Is it a misfire or a stumble. I ended up swapping all of the components on mine to figure out the sparkplug wires were shot. It would only misfire under load, but idle fine, and cruise fine until adding more load. This triggered the check engine lite for cyl misfire, and would flash while actively misfiring.

Stumble

How is the knock sensor> does it stumble under load or on hils?

Coil pack??

After car warmed up.stop car.and start to go

When last time plugs and plug wires changed??

Not it is not mine. Sister in law.will change them .since i have a set

remove the airbox and the washer fluid jug to get at them easier.

When was the timing belt done? Possible timing slip issue.
