Hi all,
The other morning my dad started his 164 and it had a very lumpy idle. We suspected the plugs were bad and they were, so all 6 have been changed. Have checked for any hint of an air leak in the inlet plenumn, again nothing. Also have tested the lambda - it appears to fluctuate between 0.2 and 0.6 volts, which I think is sort of ok, I used this as a guide: Just Lambda, Suppliers of Bosch and NTK lambda sensors including zirconia and titania sensors by post
Not sure what to check now - is there a way to test the AFM? We disconnected it and the engine cut out, but the second time we tried this it stayed running. Have taken it off for a look and the flap moves freely, not much else to see, its all clean etc.
Where is the idle control valve?
This is only an idle problem as the car actually drives perfectly well. The other day on a long drive to Birmingham we did notice once that the injector light was on for a few seconds when we were on over run - did not affect the running, and it still goes better than our 166 3.0 V6!
Any ideas?
Thanks
Jack
