My previously reliable 166 has started stalling while in motion with the injection light intermittently coming on. It restarts OK and ticks over and revs at rest but stalls when in motion.
My local back street garage used his pukka Snap On code reader which showed all 6 injectors as having faults (P0201 - P0206). It also showed P0443 (Cannister Purge Volume ??), P0654 (Rev Count Cont ?) and P0500 (Speed Signal). His view was that it was 90+% likely to be the ECU (ECM) at fault. I'm not so sure.
He cleared the codes and suggested this might effect a cure. Not so. As soon as I pulled away the injection light flashed and within half a mile the engine cut out but kept going due to bump start effect. I went straight back to the garage and he found no new codes ( which is odd).
I had the ICS out a couple of days ago but can't see this as being relevant - or is it ?
Any suggestions gratefully received.

How's the battery? (and/or alternator). Always check the basic stuff first - earths, battery terminals, battery condition, fuses/relays. The electronics are really very reliable on the whole - it's usually a cheap sender, some dodgy wiring or the like at fault.

I spent a very long time chasing a fault some time back to eventually find it was a broken (cracked, not blown) fuse to blame.

HTH, and keep us posted.

Good advice - I'll check this out in the morning.

It was really good advice. I stripped off the footwell side panels and the under dash "carpet". I had a fiddle with all the myriad relays and terminal blocks one of which clicked as I pushed it together. I also cleaned up the battery terminals which weren't too bad.
I have now been out for a couple of drives and all seems well but I won't be able to breathe really easily for a while.
Thanks again for advice (probably saved a lot of anguish and filthy lucre).

Im no machanic but i had a similar problem after they changed the timing belts and water pump on the 60km service. Found it was an earthing wire issue. noticed that the wire covering had melted causing wiring to get damaged.

Fingers crossed you found the gremlin, and thanks for keeping us posted.

Just imagine how much your average dealer would charge for that fix....assuming they eventually found it after changing the ECU etc etc etc at your expense.......

Final post on this subject I hope. I have replaced all the carpets and covers and all still seems well.
As ChrisS says above I seem to have dodged a very expensive bullet. Just how much might a dealer have charged - £1000 or £2000 perhaps. What do you reckon ?

It doesn't bear thinking about. You might get lucky and find a reputable dealer (!) or specialist that would only charge for the work done, but typically they just keep swapping bits out until they find the culprit. Funny that they never seem to re-fit the perfectly good items removed though.

Glad you solved it!
