get the boot there, now and save it.
THE WK jeep that is, USA?
how many miles since a full tuneup?
the full manual is there.
i have a 2010 WK, same car
but mine is 2 cylinder less , cut off, 3.7...
did you replace the spark plugs yes?
and when out are the COP boots ok.? the coil pack have boots, (sold separate too) and go bad on about 2nd set of plugs at 2nd tuneup.
the ends get all carbonized and fail. looking at them and bingo they are bad.
see page 1599 in that book about. COP (coil over plugs, 8 coil packs)
all this is tune up stuff, when you do that most cars stop bucking..
99% do, if not it takes scan tool to find it or a SCOPE.
the age oil shorting the spark plug out to find a dead plug as you can see in not easy. deep down there, but they sell kits to do that, extensions.
the scan tool will show P03xx codes... 300 is random misfire. the codes are good to know, but a tuneup fixes most causes..
