Way to go. Absolutely no car information whatsover.
Looks like an IAT plug.

 

My bad bro its a 95 eg sedan lx with a d16z6 when I was changing out my prop valve I noticed it just hanging there lol no cel tho

 

iacv, iat, or tps all i can really think of. by the firewall. check around the manifold.

 

It's from either IAT, IACV, or EVAP solenoid. If that is for EVAP solenoid and if you plug it into IACV, you'll have idle problem. Same goes for IAT. If IAT and/or IACV plug is not plugged in, the code will throw.

Z6 is the bottom one. There's two place where that plugs in. Top one is EVAP solenoid. Bottom one is IAT.

 

Colors look like evap, check out this thread to find out

I just checked and the evap solenoid is bypassed and the hose goes straight to the evap canister is that a problem?

 

 

 

If you live in CA, it's illegal.

 

I'm up in Washington and I passed emissions with no problems I was just wondering if it would affect anything like gas mileage ?

 

It's just for emission. You're fine then.

 

looks like a iac plug bud

 

OK cool thanks for the info guys I think I'll try and get one at the pick and pull just in case

 

someone could steal your finger prints from that picture. . .
