intake manifold vacuum lines and 'long term fuel trim' code 232 850 1995

posted by  someone claiming to be ksg on  Thu Jul 13 08:40 CST 2006 [RELATED]

Several posts regarding the intake manifold have mentioned a vacuum line and elbow on the manifold near the power steering pump (this is an 850 NA).

When removing and replacing the intake manifold recently to service the oil separator I did not find such a line - the only openings or lines on the manifold itself are near the throttle body and connect to the vacuum tower and the EGR valve. There is one other that I think must go to the fuel vapor canister or the power brake booster.

After doing the service the car runs as before but I get the 232 code for long term fuel trim at idle. I think this could be due to a vacuum leak.

Can anyone describe the vacuum line near the power steering pump so I can look and see if I might have missed it somehow? Also what does this connection do?

thanks to all!
