Just wondered if its worth changing the ignition leads on my 99 ph2 twinny? not sure if they are an issue on GTV's or not, and i'm sure its still on its first set.

she's running quite lean and a bit lumpy at idle but has been sat for around 12months and i'm slowly but surely giving her a new lease of life.

Check their condition, if the rubber is split/cracked then change them... otherwise don't bother.

Can you hear/feel it misfiring?

they look ok if i'm honest, its only due to the car running rough at idle and running really rich (know i put lean but i was shattered when i posted earlier) and drinking fuel... since heard its probably the o2 sensors, just asking for advice now on how to change them etc

You only have one lambda on a 99 - its underneath on the exhaust.
I'd check spark plug condition and if you can borrow another MAF ( Bosch ) and try that first
