So i just dropped my JDM D15b into a 95 four door. Everything is plugged right, everything is correct. Car loses power when rising in the rpms, speedo goes crazy, tach goes crazy(never had a problem with the b7)
Codes:

10 (IAT Sensor)
14 (IAC Valve)
20 (Electronic Load Detector)
21 and 22 (Vtec isn't hooked up because i have a LX non-vtec wiring harness)

It's almost like mayb a clogged injector or spark problem? I don't know. HELP.

 

I don't think its possible but are the IAT and IAT switched around because they are the same plug. ELD possibly that you have a loose or ground not hooked up.

 

Yes IAT Sensor is in correct place and IAC valve is plugged in correct place.

 

All grounds are correct also.

 

I definately seond the switched IAC and IAT plug. It's an easy mistake to make and the wires are similar. Just triple check to be sure

 

Just triple checked. Haynes Manual doesn't lie.

 

when i swappd a d15b into my car i was throwin IAT,vtec and other cells also. i replaced all these parts but was still throwin the cell.. realized the ecu wiring wasnt fully connected.. just a thought before you risk wastin money on stuff not needed like me..

 

ECU is fully connected. Also, I dont know if this matters, I'm running the jdm P08.

 

I'm one for testing it with a known working IACV. This way you can tell if you got a ground problem or plug problem someplace or if you simply bought a motor that has some **** wrong with it. At least find out the resistance that the object creates and do an ohmz reading and make sure it's reading that.
