Ok, I think I have a doozy for you guys. I have a 1995 Maxima. I ended up blowing a head gasket on it and pretty much destroying the engine. I ended up buying one from the junkyard which is a 1996 engine. Now I had a starting problem with it but I pretty much have that part figured out now.

Now this is what my engine looks like


And this is what my engine bay is like with the evap canister


Now, my wire harness and all doesn't have connectors for some of these, more notably the absolute pressure sensor, the MAP/BARO switch solenoid valve, and the evap canister purge volume control valve. And maybe a couple more. My question would be, since my ecu isn't taking into account these things, since its not made to detect those, is there anyway to go around them or remove them so the ecu isn't trying to compensate for something it knows nothing about?

It's not throwing codes for any of these because its not looking for them of course. But my car has had a rough idle the majority of the time and i'm thinking this is a good possibility since it may be trying to compensate for something its not suppose to.

Any help or feedback would be greatly appreciated. You all have helped me in the past and I like how good everyone is. Thank you

 

You have a 95 Fed spec, which is rather rare. Remove all the donor parts you don't need and reinstall the emissions equipment from the 95 engine. 95 is more mechanical and less electric in regards to the emissions equipment.

Also clean the throttle body along with the idle air control valve and check the TPS and adjust if needed.

 

Well I no longer have the old engine. Is there anything I could do? I know junkyard would be next for anything, but any specifics as to what I can take out, if I even can?I already cleaned TB and IACV.

 

As stated above, you should have remove the parts from the donor and installed the parts from yours that match your vehicles emission layout.
