Unplug the battery for a few seconds and run the codes again, see if it comes back ASAP.<p><br />O2 sensor codes.... it looks like they're not pluged in..... or maybe you got the wrong ones? They are grounded to the back of the drivers side head. Follow the braided steel strap and see where it bolts in. In the same bolt there should be another wire that grounds the O2's. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>IKE</b> <br /><small>Member # 435</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(2002,1,10,19,24,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I have vacum to the egr i pull the tube and there is air so its not that!!

The EGR only opens durring steady cruise or durring the engine running EEC test. To see if the EGR is getting vacuum, run the engine running test with your finger over the EGR vacuum line. Half way through the test you sould feel suction from the line as the EEC tests the EGR. If you don't feel the suction, then your problem is down stream.<p><br />I have a feeling all your codes are due to one problem. MAF, O2's, EGR. It shouldn't be hard to find another 5.O and swap MAF's for a few minutes to help trouble shoot. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>IKE</b> <br /><small>Member # 435</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(2002,1,10,20,6,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Hey there is vacum at idle what would cause this !! know Im getting somewhere!! <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>IKE</b> <br /><small>Member # 435</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(2002,1,10,20,7,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I have vacum at idle!!!
