Stupid egr code
My sister just went through the p0401 code
First it's important to know if it's too much air flow or not enough air flow. Be aware the repair shops are just going to start throwing parts at this issue and hope they get it with the first try, this is a difficult one to nail...
P0402 code ewww
Hey guys I've been reading your thread about this code, here may be a silly question does it narrow it down any if I'm getting terrible gas mileage as to egr, vsv, etc. ?
Any help very much appreciated.
