| well, after reading several other posts on the EGR valve, I am not so sure that I do have one. There is something that looks like the EGR valves on gasoline engines, but I do not think that I have the vaccuum pump things. I am probably mistaken about the EGR, I will take another look at it.
I have done several google searches for the MAF, where do ya'll find them? I do not mind paying for one, but what does it really do? I just noticed my mileage DIE when that light came on.
