94 Del Sol Strange Revving Up & Down
Hello all:
I have a 1994 Honda Civic Del Sol. Recently the car has been revving up and
down and up and down during idle. In addition, when the car is doing this it
begins to overheat immediately, even during frigid temperatures and the
heater has stopped getting warm. The engine is a SOHC VTEC.
I have never experienced a car doing this. Any advice?
TIA.

check the coolant level - inside the radiator, not the expansion bottle.
should be full to the top. check only when cold.
when refilling, use a good quality long life anti-freeze diluted with
distilled water.

-------------------------
You've allowed AIR into the cooling system by forgetting to keep the
system full enough. The air will displace itself in about three 'trips'
as long as there's some reserve in (of all places) the reservoir. Like
Jim said use good coolant, preferably HONDA premix and do it _according
to the owner's manual_. Fill the coolant reservoir to MAX and add as
necessary for three days. It will appear to 'sip' coolant so you have to
add some each morning.
Don't overheat a HONDA ! !

If it's not low coolant, it's a bad temp sensor.
