Ok. Where are you located?

Realistically, if it's throwing an engine light it's going to be throwing a code. Which literally gives you the problem with the car. Instead of trying a million and one things that it's not before stumbling onto it.
You dont have a code reader, pay the diagnostic fee to get somebody who does have one to read it.
