For a good few weeks now, my MPG has dropped quite dramatically (MFA is showing an average of 39.8mpg now ), and the engine performance feels different - feels flat at low revs then comes really alive as I get nearer 4k.
These are very noticeable differences.
On Friday, I drove somewhere local and noticed the car "felt different", it felt more eager again at lower revs. On Saturday we did the usual trip to the mother-in-laws, and my economy had perked up again almost back to previous levels (this is a route I've driven many times).
But today it felt flat again, mpg had dropped again, and to cap it all it there is now a noticeable amount of smoke under hard acceleration, which wasn't there before.
Puzzled now. For a long time it's made a hissing noise - audible from inside the cabin - as I accelerate and engine revs rise, but I'm buggered if I can find where it's coming from.
Wondering if it's a suspect MAP sensor or some other obscure problem...
