thanks for the pics guys. now on the pic that dr.latino_999 posted it on the map sensor (lower plug) it's just hangin there can you guys tell me what is that doin to my car? also i conected all of my vaccume lines (except whatever the map is for) and i hear a vaccume leak and it sounds like it's comin from the intake manifold area.......does anyone know what that could be???

 

Are you referring to the plug hanging on the back side of the intake manifold near the firewall? Mines like that too, I forgot that plugs name, its an extra plug we don't need with our DOHCZCs. Lemme find the thread. brb - Darrell

You will see that the Vacuum Hoses for the STD/DX and possibly Si aren't exactly in the same places. But here is how they should be hooked up.

Sensors on the firewall...

The 2 vacuum hoses from the MAP Sensor and Purge Solenoid Valve (PSV) are to be joined together with a "Y" Connector. You should not leave the hose from the PSV vented to the atmosphere because it's job is to open up to release the trapped hydrocarbons inside the charcole canister into the engine's intake manifold so they can be burned up. If you do not have this system hooked up properly the HCs will be released right into the atmosphere which is horrible for the environment. So do your small part and make sure you hook it up correctly.

Help any?

 

the plug that is undone on my car is the bottom plug on map sensor(nothin there to plug) what woud that do to my car? the reason i ask is because i hear a vaccume leak and i think it has to do with that hanging plug????

 

Jason, u had the sohc d16z6 a while ago, right??? Possibly they removed the map sensor from the firewall, becasue you were prolly using the one on the throttle body with the z6, just a thought.

PS, will u be home for thanksgiving?? You can come buy and get one from me.

Ryan</TD></TR></TABLE> i guess so, i dont have a sensor(map) so can someone tell me what is the map sensor for? because ive all ways had idle issues after the swap and i need to know if no map sensor=bad idle/vac leak????
