question about cto's

[clarkja]

Hi,I've been trying to research it as much as possible before asking but I'm curious if this is right.I recently became the owner of a 90 gw that does not want to stay running when you start it.After it gets warmed up it's fine,except the idle seems a little fast.I found the info on cto's and looked at mine,now I'm curious if the two on the front of the engine are supposed to be the same or not.Their both yellow 3 port's.Does this sound right?

No, the one on the thermostat should be red 220º one. It sounds like you're getting full manifold vacuum all the time (which would happen if you had two yellow ones). Check the link in my tech pages below for alternative part numbers for that piece.
