I'd say go get the codes read. thats why they're there, easier than guessing what it *could* be.

Spend $60 on a code reader. Absolutely the best tool for cost I've purchased. Just get the cheap one from O'Reilly's. It is blue, and does everything you need.

just go to oreillys, autozone, advanced and they will scan in for free...then come back and give us the code and we'll see if we can then help.

No need for a code reader just use a paper clip. Jumper pins A and B, the two top right ones. Stick the key in the ignition and turn it forward but do not start the 'Hoe. The engine light light will flash in different sequences telling you what codes you have in the ECM.
