Clean it up good and re-install it. Clear the codes and see if it comes back. If it does, look into replacing the EGR valve. The EGR valve itself fails more often than the EVP sensor behind it. I find that the EGR valve needs to be cleaned every 15-20K miles on 5.O's. <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>1FastLX</b> <br /><small>Member # 1178</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,11,19,16,48,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Gray LX<br /><br />i replaced the evp and cleared the codes.<br />but you have to pull the codes for your to be sure its the same problem like mine<br /><br />lates <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>graylx</b> <br /><small>Member # 3919</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,11,21,20,34,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Checked the codes...Code 31.
