There we go........four days into ownership and a problem occurs ! :(
Starting from cold in the morning it (2.6 V6) fires up ok, but after 10 seconds or so revs drop and runs rough. Struggles to pick up for first 50 yards then it's off, no problem and idles ok after that.
Does feel hesitant at low revs generally, but once above 2500 revs it's fine.
Throw me a checklist please. Will check for oil in plug wells, but wondering if there's an inlet problem (gunk blocking a butterfly valve or similar - my old XJ40 Jag had a similar issue).
Cheers in advance.

Give it a service,check plug wells for oil etc
-
Any other suggestions ?
Am thinking it may be breather related, as once on the move and first past 2500rpm, the problem goes and it ticks over fine. Being the 2.6, am I right in thinking it shouldn't suffer the old woes of the 2.5 dis pack corrosion problems ?
Oil is nice and oily - no mayo here !

2.6/3.2 have two coil packs, both in the firing line for water ingress issues :y
-
May wish to remove the throttle body and take the plates out and give it a good clean.

Thermostat and coolent temperature sender.

I am getting a coolant level message on the dash, but the level is fine and hasn't budged - don't think this will affect anything though - assume the float in the expansion tank is just stuck ?

Pedal test shows MAF sensor and various misfires. Codes cleared and only showing 110 now (MAF).
One of the intake pipes has tape round it, so may also be leaking/drawing air, so will replace.
