There are literally a thousand and one reasons for the Check Engine light to come on. Going to the store and buying parts in hopes of hitting the right one is a poor troubleshooting technique. You really should buy an OBD II Scan Tool to pull the codes so you know which parts to put into your shopping basket.
Hey I think my poor troubleshooting technique worked. I just got a gas cap and as soon as I started the engine the light went off.

So my advice to you guys is to go to auto zone instead of getting a scanner and they will let you know what's going on and start from there

Thank you all for your replies!
