Question about 1993 Suzuki Sidekick
To fast hot and too fast cold that it?
well here is normal, its a G16 engine, a Vitara with Sidekick badge.
G16 in cold weather, start and race idle at about 1500 rpm
or more if in ALASKA, you never said that or how cold it is.
the IAC valve is thermal, it and opens more colder, a fact.
the 8valve engine (black steel top) is faster. cold idle
then drops in a few seconds, to 1500rpm
at this time, the ECU brain does NOT control idle speeds at all.
the the engine warms up by virtue of the thermostat
as it warms to 150F to on way to 180f stock temp.
the ECU then takes control of the idle speeds.
got that so far?
so at 180f the idle is 800 rpm (800 is hard coded in the ECU,
ad ECU regulates this, unless you turn on the A.C , and if that happens 1000rpm is called up.
if not the ECU cant control it or the ECU is in limphome mode or worse.
if you insert the diagnostic jumper
does the CEL lamp flash 12s
see this paper clip this is your only scan tool.
it is crude but that is all you get until 1996.
