Hi,

Recently in the cold period now i have the 2 symptoms.

1) High idling at cold start 2000 rpm, sometimes it rises a bit higher to 2200 and drops again.
On warm motor it drops to 850 rpm and even lower like its almost stalling.
Can this be caused by a dirty IACV valve or bypass valve?

2) On cold temperatures outside: 6 degrees C
Running in high load the temperature sensor of the water lowers a bit, 0,5 cm (never to 0) to rise again after i stop the high load.
Maybe this is normal behaviour if not is it caused by a bad thermostat?

Thanks in advance.

It sounds like you may have a cooling system problem. You may want to try replacing your thermostat. You can also try cleanign your IACV.

Great thanks Spunkster
