Long term fuel trim

[mb450]

I've noticed my chimaera has been drinking fuel more than usual.
Hooked up rover gauge and the long term fuel trim is adding heaps of fuel. The "odd" side is getting more adjustment than "even"

I've checked the lambdas and they're switching.
I've swapped plugs, ht leads as they were well overdue.
It idles very well and I cannot hear a misfire.

Throttle pot seems fine.

The only thing I'm thinking is the camshaft. At 75k it's still running the original gear.

Anyone got any ideas?

Could be that, is there a reliable way to test?
I checked the water and fuel plugs weren't switched around.

Ok will order replacements for both

I'll post some screen shots up in a bit not 100% sure I'm reading roverguage correctly!

Here's the long term and short term fuel trims - this was after about a 20 minute run.

Anyone got any ideas on what I should look at here?
