98 XJ 2.5L Sport Cherokee not going over 30-40mph
 

Hi guys and gals

I've still got an issue with my Jeep, it dont wonna know about going faster than 30-40mph, just stutters when you try floor it after that, but before that speed its perfectly ok, gets upto 30mph ok, starts ok, low idle at moment still, would that be linked you think?

Thanks! :)

PS This is a manual transmission.
