Your truck has a timing BELT that should be replaced every 60,000 or sooner and multiples of that going forward to prevent damage to the valves.

we need more info on this vehicle yr make model engine 2wheel 4 wheel auto manual

sounds like engine is out of time

could have faulty throttle valve control motor or throttle valve position sensor.

But it started and ran fine before this? If YES, then the answer's patently obvious eh? The belt was put on incorrectly, or more accurately, the timing has been set up wrongly. Sadly it seems you'll need to get someone to check the timing and get it reset properly. Best of luck!

Please see my tip at http://www.fixya.com/cars/r5932051-check_engine_light_check. These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

Scheduled Maintenance Services, for most Cars, has to be done at 30K, 60K, and 90K. Hyundai dealer recommend to replace the timing belt at 60K Service.
If you wait, one of two things could happen: Nothing, or the belt could break and you would be out thousands to repair the engine instead of a $400 hundred to replace just the belt. If it breaks, there will be damage done to the valves and various other internal components, which will not covered under warranty. The problem is that the Dealer would charge you between $700-$800 because they would also replace the water pump at the same time. Or you can buy the timing belt and change it by your self. To do so, you nee the Haynes Repair Manual specific for your car another equivalent.
