I bought a 2003 TJ a few weeks back -- and have taken it out on the highway a few times.. I have to say the 4.0 has lots of get up and go for city driving -- but on the highway -- what happened?!?! It's great up until 100Kms (65miles) ish but after that it seems to really have problems -- it's a chore to keep it at 120 in 5th gear and come any real hill it's pretty pethetic even gearing down to 4th or even
3rd..Is it just my jeep or is this a common thing -- does this motor really suck that bad on the highway??
