SOURCE: 1997 buick lasabre custom high idle, transmission, stalling

had same problem i would check the Idel Air Valve and also check all of your vaccum hose lines makeing sure there are no cracks or splits in rubber connectors if there is repair immediatelt because over time they start to dammage the internal parts fo the engine and if youve replace tps mass air etc. sounds like a vaccum hose problem

Rinnai temperature flucuates water

Hook up a professional scanner an see what the actual temp of the engine is . Coolant temp. sensor is a input to the PCM - engine computer . Go to harbor freight tools an buy a Non-Contact Infrared Thermometer With Laser Targeting What's the temp at the thermostat housing . Does the temp.'s match an the gauge is off . Testing an not guess as to what the problem is.
The PCM sends temp. info to the instrument cluster via the class2 serial data bus . I have seen a number of GM instrument cluster issue's over the year's . Could be a electrical problem , an the engine temp is correct .

My 2001 Buick LaSabre "eats"

If there are no coolant leaks then check your engine oil to be sure it is not over full or foamy because if there is coolant getting into the oil it will cause irreversible damage to the engine. If the engine has ever over heated the head gasket/s could also be leaking and will need replaced.
