Scored this e30 for cheap but it isnt running right.
anyways did a compression test turned out good
the thing bogs and runs like shit when the ICV hose is plugged into the intake elbow.
tested : wires,ICV were both in spec
new plugs and this thng is running pig rich but leans out a bit when i pull the ICV hose out
anyways this little thing on the airbox? what is it?
it was taped up and shit when i bought it with just some wires going into it.
is there a vacuum line that goes into the AFM?
what is the purpose of this relay thingy? does it do anything with idle or fuel circuits?
Thanks in advance.
