CEL codes

[timstone]

If I were to make a video and post it up...could you guys help me in figuring out the codes that my truck is spitting out? I can't seem to get it down...I used to be able to do it but I wrote a few down and none of them matched up.....

Here is the video...can anyone help???

well i'm no mechanic but from what i understand if you get a blinking check engine light then you have a major problem....but if it comes on and stays on its supposed to be not as major.....thats at least what my girlfriends old car used to do...and thats what the mechanic told us. Good luck.

I think you misunderstood my post. This is my truck performing the KOEO test. I couldn't figure out what codes were being shown but I think I actually have it down to code 41 (System Lean) which sucks because there could be several things making that code show up.

I've tried spraying carb cleaner around the intake and didn't have any vacuum leaks there. I don't hear any vacuum noises from the engine bay so I think my next steps are to check the EGR and MAP sensor....only problem is that I don't have a vacuum tool to test them.
