Cyl 1 misfire and revving up to limiter on start up

[LTEpic]

Hi,
I've developed a misfire on my engine. When diagnosing I've removed the inlet manifold and swapped the leads around with 2 of the cylinders.
Put everything back together to see if the fault moved on to other cylinder but now as soon as I start it, it revs up to limiter and wont idle.
I've ordered a set of leads and a coil pack but I'm worried about the revving up.
Checked for faults and its only showing a misfire fault and nothing else.
Please give me some ideas as I'm 200miles away from home and need it sorted as soon as possible
Many thanks
Mantas

Air leak on inlet manifold will cause it to rev up.
Did it on mine when I forgot to reconnect the servo hose

trapped lead under the upper inlet giving an airleak, egg seal fallen off from under the upper inlet, vac pipe missing from the servo (unlikely as they don't rev that high) or upper inlet not seated properly. they can feel seated but not be.

This egg seal.. one where a port goes on rocker cover?

Not relevant to the original fault, but does it rev to 7k rpm without any throttle pedal input?
What is the fault code that is being displayed.
My thoughts regarding the revving up is that you have disturbed the wiring/plug to the throttle body.

Just confirming you did not mean the 3K limp mode limit.

Update:
Replaced the coil pack and leads, old coil pack was cracked.
I went for aftermarket parts as I dont have money for genuine now but will buy genuine and keep them until these blow.
Also fitted the egg seal which cure revving up, no idea where old one went.. probably inside one of the cylinders now
