check engine light stays on

Check the diagnostic codes in the engine module, this will tell you exactly what to check. Once you have the code, perform a search here or on Google to find out what to check.

You'll need a scan tool that connects to the OBD port of the car, its not something you can do manually. Thats unfortunately the way cars are now, all computers. If you have the trouble code from the scantool you can search on repairpal or the internet for the code to find out what the actual problem is.

Its on telling you something is wrong..Thats why its staying on.......Boy o boy
