2011 Liberty jerking uphill

[Martin059]

So I've been reading on the web so I'm guessing this is normal for the Jeep Liberty to jerking/misfiring when going uphill around 55/60 mph.... if I give it a little gas when doing 55 uphill to maintain it kinda stops. It's just very weird. I never had a car do that before.

This is not normal to be jerking / misfiring going up hills , not at all
Have any extra load or is it dogging down?
Tried running with OD off ?

You may have a throttle body problem. I would also check to make sure you have good spark plugs and also good gas.

I replaced the spark plugs and it stopped...was @ 85K when it started

Hoping that was about the 3rd spark plug change LOL
