I would hold off 'til I did more diagnosis, especially @ $120 a throw. Plus a bad plug or lead is not something you would 'drive through', ie only be evident in a specific or narrow band.
Check both ends of the MAP sensor hose (and FPR hose), not just the sensor (or FPR) end. The engine side sees all the heat, and it would be more likely to harden and lose contact pressure.
Checking the resistance of the leads with a multimeter will not tell you how they perform under load.
Yeah after thinking for a moment decided to hold off in plugs and leads, did test the resistance and all came in around 2500 ish so well below the 12k range
Did however replace both vac lines again for to Tb and Tb to map, no change
Went out and had a check over the engine wiring etc maybe a earthing out sensor wire or something silly,
Couldn't find anything visually, neighbour came over and was having a chat gave the engine a rev to find the stumble spot.. and sparks are being thrown just beside the crank angle sensor...
So 80% sure under load the balancer is shaged and is "strwtching" causing the trigger wheel to contact the sensor
Sound like an issue that would cause the stumbling under load ?
Either way new balancer and sensor has been ordered as the rubber is all cracked
