This afternoon I gave the Mondeo's Mass Air Flow sensor a clean. It's a quick 15 minute job and it's another of those things that gets a little dirty as the miles go by and will affect the smooth running of the engine.

It wasn't as filthy as I was expecting after cleaning out the EGR, which shows that the air filter is doing its job.

Nw I just need another day of good weather to pop the inlet manifold off and give that a good clean out.
