Hi, welcome to Just Answer. I’m Ron and I’ll be helping you today.
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

So you know that it is time to scan the computer for codes and data. there are a number of things that can be causing this from the computer to the fuel pump to a bad/plugged CAT if you're running too rich. Always find out why that light is on when it comes on, this only leads to more expensive repairs later on. Let me know what the codes are and we'll go from there.

Thanks, Ron
