Got one for £9 delivered so well worth a punt. I'm waiting on dropping anything on the EDU unnecessarily now, hopefully will get the proper diagnostic done tomorrow too or at least over the weekend. I really need to invest in a half decent ODB scanner for this type of thing is just something I put off and put off. If you managed to diagnose this in one hit then mate I owe you a few beers at the very least. When i end up buying some of your bits I'll make sure I bring you something from the right side of the Pennines to whet your whistle.I'm an armchair-theory type as I am (a) quite lucky with my 1.7 and (b) useless in the practical sense. After a couple of years here, I wonder if there might be a problem with your MAF. iirc, with a burgered MAF the engine management will default to a cold setting which ties into your findings. What I do know is that cheapo MAFs are not liked by the C/Combo at all so buying a £25 new one is no help and the Bosch is eye-watering to buy, especially if it's not the problem. So, I'd hope that someone more useful than me chimes in but it's worth looking at a used Bosch (GM 0281002180) around £10-15 posted as a swap-it-and-see that also is a handy fallback spare to keep nearby.
