2006 Ford 500 SEL 3.0l. I had constantly Engine Light when driving. I have changed the battery, rail fuel pressure sensor, and AMFSensor.I have drived half hour no engine light. After an hour I have started car and engine light was righy there. HELP PLS..

 

Since many problems can cause the check engine lamp to illuminate, you might have your vehicle checked for codes to provide some direction as to where to start checking..
Places like Autozone will provide this service free of charge..

 

Thank you for the information. Just one more quick question, is it true that after new battery installed Engine light illuminates until ECM gets all the DATA. And according to google it may takes several days?

 

might be worth taking it to a mechanic if it keeps happening
