I'm doing my MPFI swap, messed something up and it's not working. Kind of chugging and doesn't want to stay running.

All wiring quadruple checked. Everything.. except the connectors. Seems I'm missing one and need to figure out where things go on my intake manifold.

Here's a pic.. what are 1 two and three, and if someone happends to know the color of the wires that the connectors go to, or if I even need all of them, that would be great help, thanks everyone!

 

Is that from a 3rd gen civic?

 

1 - EVAP purge solenoid

2 - IAT sensor

3 - MAP sensor

is that a D16Z6 mani ?
and your car is a 4th gen ?

Ya.. My car is a 4th gen hatchie, and that manifold is from a 5th gen.

I think this is where my problem is coming from.

It seems I only have three connectors from my DX hatchie. The EVAC, the TPS, and "another one" that is white and I don't know exactly what it is. :-/ Maybe IAT?

This manifold *WAS* running on the same setup in a different car, but I can't seem to figureout what the problem is.

I know it was running without the map sensor on top of the throttle body. But, I don't know if it was using all of those connectors from the DX harness.

 

not running properly , unless you're using the MAP on the firewall from your old setup.

 

Ya.. the MAP sensor on my firewall is what is being used now.. I just need to hook up vacuum lines to the intake manifold to make the MAP work from that one right?

 

the MAP sensor on top of your TB is what needs to be used.
extend the wires and use that one , ditch the one on the firewall.

 

i believe so, but the better thing to do is extend the wires from the firewall mounted one and use the new map sensor on the manifold.

also, number 1 should the evap purge, which should currently be on your firewall. it'll work fine as long as you run the vacuum lines correctly.

 

OK, minor update. I checked the voltage of the EACV, and it doesn't seem to have voltage!

My Haynes (worthless book) said to check for an open circut between the positive wire of my EACV and the PGM-FI main relay..

Uhm, how the heck do I do that?

 

read the book , the PGM-FI relay is above the left kick panel by the hood release.

 

its not throwing any codes ?
