Good luck!

The PO said that he personally replaced the injectors and that has worried me since day one, since the Mon, 07 Sep 2009 08:00:36 GMT RMSundberg http://autos.groups.yahoo.com/group/318iE30/message/2715 http://autos.groups.yahoo.com/group/318iE30/message/2715 Expanding on what Brian has said, cold idle problems are often the result of improper air/fuel mixture. The cold start valve squirts extra gas into the intake Mon, 07 Sep 2009 01:20:27 GMT bjm2cv http://autos.groups.yahoo.com/group/318iE30/message/2714 http://autos.groups.yahoo.com/group/318iE30/message/2714 When I hear about an idle problem with this car, I immediately think about vacuum leaks or a sticking ICV. For the first one, you have to work through all the Sun, 06 Sep 2009 18:53:43 GMT dubbie8382 http://autos.groups.yahoo.com/group/318iE30/message/2713 http://autos.groups.yahoo.com/group/318iE30/message/2713 So I am new to here. My name is JD. I have an 85' 318I sedan. All stock. So I have been fighting an idle problem since I got the car. I have put enough new Sun, 30 Aug 2009 11:46:20 GMT bjm2cv http://autos.groups.yahoo.com/group/318iE30/message/2712 http://autos.groups.yahoo.com/group/318iE30/message/2712 This sounds much like the idle control valve sticking, or at least not working properly. It couldalso be the idle control module malfunctioning. Either one Thu, 27 Aug 2009 22:58:23 GMT Randy http://autos.groups.yahoo.com/group/318iE30/message/2711 http://autos.groups.yahoo.com/group/318iE30/message/2711 Yea, its a little more than a couple hundred.  900 to 1200 rpm... so about 300.  But really irritating.  Thanks for the reply...

Chances are it couldn't be removed or as Bob says a new exhaust pipe with O2 hole was Thu, 27 Aug 2009 06:09:14 GMT roosno2 http://autos.groups.yahoo.com/group/318iE30/message/2709 http://autos.groups.yahoo.com/group/318iE30/message/2709 My guess is the reason you have two O2 sensors is that they couldn't remove the sensor on the manifold where it is supposed to be and just cut a new hole and Wed, 19 Aug 2009 08:18:28 GMT RMSundberg http://autos.groups.yahoo.com/group/318iE30/message/2708 http://autos.groups.yahoo.com/group/318iE30/message/2708 Officially, the O² sensor was placed on the exhaust manifold on the 1984 model 318i cars. Officially, BMW moved the sensor to the down pipe later, for the Tue, 18 Aug 2009 20:57:45 GMT Randy http://autos.groups.yahoo.com/group/318iE30/message/2707 http://autos.groups.yahoo.com/group/318iE30/message/2707 Thanks so much for your reply Bob. My car definitely has 2 O2 sensors.  And they are both 3 wire.  The one on the downpipe is hooked up.  The one on the Tue, 18 Aug 2009 20:31:20 GMT RMSundberg http://autos.groups.yahoo.com/group/318iE30/message/2706 http://autos.groups.yahoo.com/group/318iE30/message/2706 Hi Randy, Why would you become a member of this forum unless you didn’t have a question? :-) You didn’t mention if your problem was with warm or cold idle, Tue, 18 Aug 2009 17:52:34 GMT Randy http://autos.groups.yahoo.com/group/318iE30/message/2705 http://autos.groups.yahoo.com/group/318iE30/message/2705 My bad.

Comes off the same bundle as the 2 coil wires, but just hangs. Has a squarish connector, plugged into a connector, but no wire going Tue, 18 Aug 2009 16:52:22 GMT Randy http://autos.groups.yahoo.com/group/318iE30/message/2703 http://autos.groups.yahoo.com/group/318iE30/message/2703 Well, I just became a member... so HI.
