Oregon | If it has been idling a lot in cold temps, it could be wet stacking. If that is the case, check the oil for fuel dilution and, if the level is rising, change it. Again, if it has been doing a lot of idling, check to see if it has been getting up to operating temp, change thermostat if necessary, and stop letting it idle for long periods.
If it has not been idling a lot in cold temps, ignore all the above. | |
