I have swapped the engine in my 1995 civic VX 5 speed (D15z1) with one from a 1998 civic HX (D16y5) that had a Continually Variable Automatic. I used the 5 speed and wiring from the 95 engine. I had to change the connectors on both the Intake Air Temperature sensor (IAT) and the Evaporative Emission Purge Control Solenoid Valve (EVAP) since they differed from the 95 wiring harness. They had only two wires each (95 and 98 versions). The 95 distributor is close but won't fit on a 98 head. MSD makes a conversion connector so the wiring didn't have to be changed. The swap was rather straight forward. No mechanical changes had to be made.

I do have one problem I'm hoping the form can help me with. The Idle Air Control Valve (IAC) on the automatic version of the 98 engine has two solenoid control inputs (windings) plus a common. There are three wires in all. The 95 and 98 manual configuration is one solenoid control input (two wires in all). The engine seams to run fine but idles like crap. I currently don't have the (IAC) connected. As expected I only get one code in the computer, #14 Idle Air Control Valve.

Can I use the dual input (IAC)? If so which input of the two do I use, or both? If I must replace it will a manual transmission version will it gist swap-out with the original one?

Thanks
