Jerseyville,IL | Whats water temp at Idle ? Should be at least 165 to 180 degrees .
Whats ambient air temp?
The injectors might not have even spray pattern .
Has the engine been pulled hard lately ?
Has it had bio fuel let set in it for extended period ?
If so pull injectors and test.
Unless someone has messed with the pump I kind doubt timing is off .
The timing advance might be sticking or stuck , but would think that
would show up at high also.
Hope this helps
