Gwil, Have the air/fuel mixture checked. Also, the AIC valve might be duff. Neither are expensive and should be done just to rule them out. By jolty, faltering, etc, do you mean when you declutch and apply the gas in the lower gears the idle drops right down and the car almost stalls? [On mine, it occurs after a cold start within the first 5 minutes and only until the car is warmed up.] If so, see above - my 900i does exactly the same now & again and just takes a couple of minutes to sort out by my mech. As a *very* temporary measure, you could tighten up the throttle cable a little so that it idles warm at about 900-1000 RPM - do not run it like that for long though :) Get it to a garage. The water pump is also not a big job, nor costly. Mine blew on my 900i - it's quite fun when it does go :) You get surrounded by steam and your engine get covered in sticky anti-freeze which takes ages to clean off.
