'03 Sonata 2.4L is pinging, power is a little low, fuel economyshould be better

2003 Sonata 2.4L 4 cylinder, 59,000 miles, I just bought it about a
month ago. I am getting pinging, especially in hot weather, and my
mileage should be better (I'm getting about 18 city, 26 highway, I
thought I could get at least 20 city, and 30 or better on the
highway).

Does this sound like a bad EGR?

Where can I get a service manual, preferably online?

Thanks for any advice you can give! - John

You need to set up an account but it's not hard.
