what sensor have i removed?

[gtirjoey]

right i needed to change the cold start device so i got to work taking off what i thought was the coldstart device. now i have it off bob has told me ive taken the wrong sensor off:doh:
the one i have taken off is the one round the back off the manifold it has two water pipes connected and two air pipes and one multi-plug.
does anyone know what sensor i mean?
i have been told i can just leave it off and link the pipes together is this true?
help please

is it a thin black square about 2 or 3 inches big? if so without it you wont be able to start your car from the key. i had this left off once and when connected the car started

sounds like the part mate.. would it not start or was it just hard to start

 

[gtir_pimp]

wouldnt start at all. the starter motor didnt work until that was connected. im not sure but was told it was an air/idle sensor or valve.
try starting it with it off to be sure.
