Ok new EGR Valve and still CELL
I replaced the EGR Valve on my truck and cleared the Cell well that worked for a total of about 15 miles and the cell was back on. The code is EGR EXCESSIVE FLOW. I have had the truck on the computer several times and am sick of taking it there seems like everytime I fix something something else goes wrong. I have not taken the truck and put it on the computer for this problem and was hoping you all could give me some info. So I changed the EGR valve with a new one and still Cell on so what else could I check when its giving me this reading EGR EXCESSIVE FLOW?? The truck seems to be running fine little ruff when you start it cold but no different then any other diesel I have ever had, no smoke. What else could I check on my own please help me on this the truck is killing me on dealership bills.
