New coil and its still lumpy????

[hitman_bridger]

Running out of patients with this now. Just left vw for new coil and its still running lumpy. Cannot afford to let them have a look at it £90ph.  Anyone have any ideas?

Is it possible you're driving over speed bumps rather quickly?

14£ from the bay, get a code reader and stick the codes up here so someone can have a look

and what do you mean "lumpy"

[hitman_bridger]

I do have speed humps near me but I don't go over them fast at all. What I mean by running lumpy is that it feels like its being starved of fuel. It's ok when in boost but lumpy when idleing and accelerating.  I haven't checked for boost leaks yet but will when I'm home. I do have a decat to fit still. ( was told it could be cat had failed).

Well, he said he has a new coil and it's still lumpy.

The thing is, the ignition coil is encapsulated, so they tend to be a block or 'lump'. It ought to be as much of a lump as the old one was.

Mine was the same mate, changed all coils and new maf to find out it was a split in my breather hose

A few of my friends are now saying that it is possibly a hose gone. Will definatly have a look tonight. Don't really know what I'm doing but will give it a go. Thanks everyone:)
