My 1.8 freelander seems to Rev high in neutral but when driving has power of electric band car ? And ideas

Really frustrating my 1.8 freelander will Rev high on tickover but as soon as I get driving it especially 3 gear and above I am lucky to get revs to 3.5-4 k ? Must be something holding it back ????

Any advice please , my 2003 freelander seems to be sluggish, I struggle to get revs above 3.5-4 k , any ideas to what is causing this

My freelander 1.8 seems to have lack of power , I find it hard to get revs up to 4k any ideas someone said idle valve or blocked cat , should the 1.8 lump Rev higher than 4k ?
