hi all have 2003 freelander manuel
Here's the problem it misfires but not all the time
If you start from cold you can drive as far as you want 10 20 50 100 miles no problem it's perfect idle the engine in traffic no problem
But stop for say fuel fill up approx 10 minutes on a warm hot or just warm engine restart and it misses on 1 cyclinder lacks power drive like Shtttttttt until next cold start
When it's missing lacking power etc get to 2750rpm and it clears
I have replaced plugs and both coils
It's mental

Is it losing coolant?

Pull the spark plug on cylinder 1 and 2, compare - if 1 looks clean you've probably got a head gasket or manifold gasket leak.
More likely a classic manifold gasket failure - it has a weak gasket bit right next to cylinder 1 intake port which means it frequently gets flooded.

Barely any water I check it weekly it runs under the middle as normal when it's stood for 10 minutes the temp gauge doesn't more just restart and you know it's misfiring on a cyclinder
Is the the manifold easy to change do you need to drain the coolant
Thanks

Yes easy to change, and yes you have to drain coolant, and then it needs to be bled thoroughly

Is there a Guide anywhere to bleeding
Thanks

Bleeding is fairly simple.

Fill the reservoir to full, take the bleed bolt out of the coolant rail underneath the throttle body - when coolant flows out freely put the bolt back in, give it 5 minues and then slacken it off until there's a trickle of coolant coming out around the bolt. This will grab any last air bubbles in there.
Refill the coolant reservoir.
Take out the plastic bleed screw in the upper heater hose, wait for coolant to appear and reseal.
Refill the coolant reservoir.
Start engine, run at fast idle for 2-3 minutes with heater set to full.
Shut down, wait 1 minute, repeat last step bleeding the upper radiator hose.
Refill the coolant reservoir.

Sometimes the hot start misfires are also caused by cam/crank sensors on their way out - heat soak after you shut down will often put a cam sensor over the edge and cause it to fault.
Might be an idea to get your codes read - some things don't show a check engine light if they don't screw up the emissions totally.
