Since the events described in my last post re would not start (idle control Valve 2.5 estate 1998)and my, eventually getting car running after ,I thought solving problem by drying out Dis pack etc.Today I went for test run.Car started first time as usual before Fridays problem. As usual (in cold weather)would not idle without throttle until warmed up for 1-2 minutes with light throttle.I went for a good run in sports mode and gave it a some "welly".Everything okay, pulling well etc and when I got home was idling at approx 600 rpm with no problems(as usual once warmed up) This evening started car - used light throttle as usual to warm up but car would not idle without throttle even after 5 minutes.I took car for run around estate in 2nd gear as I wanted to warm up engine but did not want to go to far from home in case of breakdown, no sign of missing or any problem under throttle, warmed up engine to 90 on gauge and then parked up, it still would not idle once foot removed from throttle.After restart with throttle and very very gently releasing throttle I finally got idle at about 400rpm (very rough and shuddering)As I had previously read Marks DTM post re bad idle(whack EGR with hammer) I tried, It made me feel a bit better but car stalled.Did paper clip test - no codes when running with light throttle - code 31(as previous)when trying with engine not running.New crank sensor has arrived now, but since I had car running perfectly earlier today and I show no fault codes when testing with engine running, could this be the problem? Would faulty idle valve just show problem at idle or would engine stall whenever throttle released and slowing down?
