Was workin on cleanin up my friends engine bay and came across this lil piece, not sure what it does or where its supposed to be mounted, but there was a line goin to the intake mani and also one down to the charcol box, but then there is a third tube that was cut and it has a bolt shoved in it...any ideas?! Its a '94 LSvtec, with b16 head and itr intake mani if that helps.. thanks

 

beats the fawk outta me...does his car idol all funny with this thing out?...*bump*

 

humm, what obd is it? bump

 

yea, if u pull any line off the intake mani, it starts to idol high...I believe its obd1, but not quite sure, since its an lsvtec..not sure what year the head is

 

Looks like an evap solenoid to me...and very ghetto rigged at that.

It idles high when you pull it off because you are leaking vacuum. Loop the lines and remove it all together.

 

is it a sensor of some type? it has a plug to it, so I don't know if I can just "bypass" it...engine light or throw a code maybe? I don't know what the hell it does...

 

Unplug the harness and see if you are getting a CEL. I have mine completely unhooked. It is just for emissions.

 

thanks Das, I'll check it out!

 

looks like the evap purge valve.

 

Keep it! That way when you turbocharge your car you can hook up a momonetary switch to it and use it as a "scramble boost" valve!

 

u lost me on that one... and thanks for the printout!

 

That is definitely the EVAP purge control solenoid, although your buddy has it hooked up incorrectly. The nipple on the bottom goes to a vacuum source on the IM, the one toward the top pointing out goes to the charcoal canister, and the top should have a hat on it, and if you cannot find one, just plug it up. Basically, just move everything there over in a clockwise direction and its all set. Dont forget to hook this up correctly or you will fail emissions. HTH
