I know what 0100 is , Mass Air Sensor but what is the Other one 04E0, I think it has to do with the EGR. But if yall have any info on it that would be great.

I havent seen either of those before. Did you make any changes to your intake recently?

 

[mattpopp]

no, I had not touched it other than cleaning the filter about three weeks ago. I got it on the way to the track Friday night. The truck is running the same

Is you EGR intact or is it gone? Thinking it may be soot on the MAF
