When i started it up the idle hangs at 1500 rpm. It will also sit at 1500 rpm when I'm coasting until I come to a stop then settles to 900. I also replaced the TPS WITH no luck. I checked the vacuum lines and they seem to look ok. I also readjusted my CAI and my maf looks clean. Any ideas?

If you did not change your IAC with a Motorcraft one, do that first because the solenoids end up failing after time. If replaced, check for vacuum leaks (spray carb cleaner near hoses and see if there is a change in idle because if it changes, you have a leak), and also check O2 sensors. I went and changed all my emissions to new Motorcraft and I still had my RPM hand. Put new intake gasket, EGR, IAC, Plugs, thermostat, temperatur sensor, a lot of changed. None of them worked, ended up being my O2 sensors went bad and it fixed my issue. I'd bet anything your issue is a old and bad IAC. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Bullitt3905</b> <br /><small>Member # 905</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(2016,9,15,20,19,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I'll try putting in anther new IAC. <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
