Hyundai xg350 L Check Engine light has come on. The car

Customer Question

Check Engine light has come on.

The car still drives well.

From a cold start, it knocks like it is out of tune, but once warm, I get no knocking...

52k miles on the 2003 XG350

At less than 8k miles, it suffered a major problem where the engine almost siezed. Since that was repaired she has just about worked almost flawlessly.

Hi there! The place to start honestly is to have the codes read.
Autozone will do this at no charge for you.Then we can see where it leads us.
There are over 500 reasons for the light to come on so it is difficult to determine why it popped on without the code.
If you would like toget the code read and post it here with me, I would be able to give you details and possible repair procedures.
