Okay, thought I'd start this separately from the the roffle thread so as to not confuse me and well, so as not to confuse me more.
Thought it would be a spiffing idea to take the Rover out today after fixeration occured recently. We know the details, so won't repeat.
Started on the button and off we Rovered. Bit of smoke from the exhaust whilst on joiny bit of the M25 but thought that was a good thing as getting rid of any remaining shite caused by the previous issues was anticipated.
Got to my location and the car was a little erratic on idle, I'd bought some self-healing multi-use tape and secured the glued together vacuum pipe I had ham fistedly snapped whilst recently fixerating. Still doing it despite that and indeed cut out a couple of times pulling up to traffic lights and so on.
I will nip up the nuts and so on just in case not quite tight enough now it has had a run. Otherwise stumped.
