    Cleaner everything up, and decided whilst I was there to clean up the MAF using Halfords electrical contact cleaner as recommended elsewhere. I forgot how tight it is to fit the Simota in place, especially with the less flexible new silicone elbow! Tip for anyone else in the future, build up the entire intake (intake, MAF, hump and elbow first, and fit the elbow to the manifold once everything is in place:

    Somewhat annoyingly, the car now does not idle at all and stalls. If I disconnect the MAF, it runs and idles sweetly and the misfire has gone.

    Looks like cleaning the MAF was a bad idea! New Bosch ones are nearly £500

    I've ordered an aftermarket one for £60 - I'd have to get through a few to make up the cost of an OEM one! May try to slot the actual sensor into the old housing when it arrives to avoid having to dismantle the whole lot again...

      I cleaned mine years ago (2014) with a gentle spray of cleaner and it was fine but have read other horror stories of them not working after a clean. There was a company selling the original part on ebay with big discount so may be worth a search.
