I have a Hyundai accent 2005. Bought it 3 months ago. Every time i push the gas pedal, it makes a noise. Noise is not too bad, but what could it be? Please help

Would you describe the noise 1 metallic/scrapping, 2 slight roar ,3 squeal, 4 something else
1,loose drive belt pulleys, something may have dropped onto driven parts
2. loose or worn air intake hose , air filter box not secured
3. alternater etc drive belts , spray WD40 onto them when revving engine , if squeal goes check condition of belts
4. can you describe it
hope this gives you a starting point
