VX Jerking issues

[xEnt]

Hi, purchased a red VX II S for 5k the other week, 195k on the odo.

It's great, however when i drive sometimes when my feet is steady on the accelerator, it feels like it drops in acceleration, then speeds up again. as if im pulling my feet off then putting it back on (jerking forward and back)

unsure on what this is, small amount of research people say might be my spark plugs or the leads, what do you guys think?

this only happens when im giving acceleration, thanks. (automatic car)

unsure if its just me, but it feels like this happens more often when the air con is on.

How fast are you going when it happens?

im going about 50-80kph is when it happens. never happens when im lower than 50.

When was the last time you gave it a service?

Its sounds like either spark or fuel or a combination of both.

Change your fuel filter and plugs and see how you go.

change both o2 sensors will most likely fix it up mine did the same thing 70kmh is when it hits lean cruise and when the o2's are tired it goes a little too lean and stumbles
