This is my first post so I hope im doing everything right..

I have a 2004 Land Rover Discovery 2 HSE. It has 122k miles on it.I havent owned it very long. It currently has a rough idle. I got a lot of misfiring codes so I sent it to the shop(no labor charge luckily.) These are the things I had done.

Codes:
P1300
P0305
P0307
P0302
P0300
P0305
P0307
P0302
P0303

Work Done:
New Spark plugs and wires
new thermostat
radiator flush
new coolant
oil change
grease ujoints and driveshaft
new coil packs
upper intake gasket
balances tires

I had a compression test done test and the results came back okay. Ive run out of ideas on how to fix the rough idle. Having a pressure test done to the cooling system to see if its possibly leaking coolant inside the engine. Im no mechanic so all replies are appreciated. Thanks in advance. Hopefully i gave enough information.

The misfiring codes are gone. After changing the coil packs the check engine light went off. Just still have the rough idle. I'll get the mechanic to check out the fuel injectors..he's just as stumped as I am. I do keep him posted with things I read in forums. Thank you
