The car when it's cold has very rough idle, and when I drive it in low rpms it seems to hesitate and popping is coming from the intake. When I get in the throttle it runs fine . I have h/c/I, CAI, injectors, fuel pump, tune, long tube headers. I have replaced, egr valve, egr position sensor, IAC valve, egr valve vacuum control sensor. <br /><br />I've been doing a lot of reading and I'm thinking it's either a vacuum leak or maybe the coolant temp sensor? I'm hoping to get some better info on the ordeal! <br /><br />It's an 86 lx <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Blow_U_In_Reverse</b> <br /><small>Member # 12298</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(2016,0,8,0,11,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> was the car converted to MAF?
