Hey guys new to the forum. how yall doing today. i have 2 questions. my check engine light keeps coming on and i know it has to do with the egr. code P0404. now heres my questions, one can you clean out the egr or do you have to replace it and two i have a tube with a red interrupted line on it. but it looks like its cut. i see a vacuum like nozzle for a line to go to. is it supposed to be like that or should i replace that. im tired of seeing the check engine light on all the time. ill have pictures of the car when i get a good camera.
