Timing Belt 2005 Tucson

[Workaholic]

Hey guys New here and I have a 2005 Tucson that I picked up for $250.....The Timing belt had broke and was replaced and now the vehicle Idles real rough and you have to keep it revved so it doesn’t stall ...it will crank up but runs very roughly as if not firing on all cylinders but once you get it up to speed on the highway it seems to run pretty smoothly.....Any ideas on what I should look for....Thanks.
