4LO and engine sign

Unfortunately, we don't have a manual on this vehicle, so it is going to cause a bit of an issue in walking through this.

However, we need to start with checking for codes and find out what is there.

If the check engine light is on, then we will have some codes. Here is a guide that will help with this:

Even though we don't have a manual we should still be able to get you on the right path and walk through this. Let's start with the codes and go from there.

Thanks
