Try a different shop if can't solve it. If you have less than 36,000 miles, take it back to the dealer for warranty repair. PO301 is a misfire in the first cylinder. Were the codes properly cleared when the work was done? He could have eliminated the injector by swapping it with another cylinder. Say he moves the injector to cylinder 2, The ecm should show po302 if it is bad. Therefore, you can move a wire (both ends) to a different cylinder or the plug. A misfire could also come from coolant entering the cylinder. How did that plug look on #1 cylinder?

It is called the "SES Light" "Service Engine Soon Light" "Idiot light" and many other terms. It indicates that there is a condition in the engine that may cause damage or an abnormality in the normal engine performance. Typically its recommended you return the vehicle to a dealer for maintenance. If you want you can take your vehicle to a autoparts store to read the "Codes" that caused the SES light to appear. They can also clear the codes to see if it will recurr again. Hope this helps some!

That all depends on what has caused the SES light to come on in the first place.Pull the codes for reference, clear the codes, then see if they come back.If the SES light returns, pull the code(s) and fix the pertinent problem.
