Lumpy 1.1

[Liam_]

Hi there,

Our 1.1 Desire was due a major service a couple of months ago. When we got it back, we noticed it seemed to be running really lumpy - the revs hunt slightly when it's idling and some mornings it sounds frankly, quite rough.

At first, I was convinced they'd used cheap parts. Removed the coil pack to find a brand new set of Denso plugs which rules that out.

Anyone have any ideas?

Dodgy fuel pump or idle contol valve perhaps? Try putting some redex fuel cleaner through it:y:
