With my Sportage 1998 once the engine has warmed up as soon as it gets to2000rpm the engine splutters, once back to below 2000rpm it runs ok.Have changed filter, air intake sensor, fuel pump, plugs.Any ideas anyone?
alright mate, i have just read your problem. i have a very similar problem but at 3000 revs. i have been told it could be a blocked converter. not sure if you can unblock this in any way or it is just easier to get a new one! will keep you posted
