As well as this issue, the gearbox seems very stiff and especially in this bad weather, 1st and 2nd take quite some force to get them in, though once the car has warmed up it's manageable but not quite butter smooth on the changes. Anyway, I have tried changing the spark plugs, HT leads and Coil packs to remedy the rough idle, but that hasn't seemed to cure the problem. My only guess would be some sort of air issue, intake manifold maybe or fuel injectors? I have attached a video of the idling showing the rev needle; https://www.youtube.com/watch?v=NUt9hIcou70 |
I get 27-28 on urban travel - 30-31 on motorway travel - when i had a failing crank sensor it dropped to 20-22 - try swopping out the crank sensor - when i did it the MPG jumped up to the figures above and while you are at it sheath the crank wiring with heat resistant cable as it is too close to the turbo and heat damage can short the Crank wiring and goose your ECU.
