For the misfire codes take a look at this link

Not an XC90 but the same engine

It's been over a month since I installed new ignition coils in all positions (except #4, which had been replaced two years ago). Despite numerous around-town and 30-minute freeway drives, P0420 has not reappeared, so I am declaring this problem fixed as a result of either new coils and/or new plugs.

I did a freeway run followed by long idling while monitoring the coolant temperature in VIDA. The temperature never exceeded 95C while idling, and on the freeway stayed around 88C. So I don't think I have a thermostat failure (yet).

Congratulations that is great news.

According to the 3.2 Repair Manual (Land Rover version) the Thermostat starts to open at 90 C and it is fully open at 100 C.

Based on the data you provided it looks like the Thermostat is working fine

Note: the ignition system will compensate for old spark plugs by increasing the energy sent thru the coils, to minimize this I replace my spark plugs every 50,000 miles. Because all new spark-plugs cost less than one coil. And the engine runs so smooth with brand new plugs.

Take care

Paul
