Recently I had the timing belt replaced on my 04 santa fe. A couple weeks after getting it back it started loping on accelaration. Upon pulling the plugs I discovered they were in bad need of replacing, having around 20000 miles on htem. After taking the car for a test drive I had the same problems. Stumbling and loping for a good 2-6 seconds before finally getting the power. Pulling the plugs back out #1 was covered with black soot. The check engine light IS on.

The car will have to be scanned for diagnostic trouble codes, that will be your starting point for diagnoses.

Thanx for the reply. I should have said this earlier. About a week after the belt was replaced, the check engine light came on. I told my wife to take it back to the shop which had done the timing belt replacment. The next day she did. Unfortunatly I didnt go with her. The mechanic sends home a paper saying that all the work they did to the belt was fine, and his machine said I was misfiring on the number 1 piston, which is what led me to pull the plugs, and how I discovered the ugly original ones.
Unfortunatly I dont have specififc codes, will try to track those down
