Cuts out or idles to high
it is a dangerous car to drive like this, "TOYOTA LIKE" dig?
if you are a toyata person the floor mats hit throttle pedal and gee....
is the dash cluster lamp called CEL glowing driving
if yes, scan the ECU/PCM read out the error numbers.
Like P0300 gross misfire. etc.
ever do a full 60k mile tuneup, ? why not, if not?
first tell the symptoms , of a hot and cold engine.
diagnosis takes facts and evidence. you offered some....
you start car cold ,does it idle fast (normal) then you drive
and idle is ok? near 800> until hot. see how that works.? the Fuelng
system works by temperatures of the engine coolant .
my guess your post is all HOT engine.
too fast idle HOT, this means the ISC (hot) is out of control
ISC is a system, not just 1 part. so dont buy an ISC.
The ISC is idle speed controls. and is the first to fail, this control
when there is any problems with,well, anything , under hood.
The ISC can get dirty and jam and may just need to be cleaned.
this is all part of normal turn up service, ask him why idle is high
i promise you , he will tell you. (ASE patch on sleeve)
the first thing to learn, on all EFI is which of the 4 systems yours is.
1999 era was only 2, AD and SD systems.
or MAP or MAF based EFI. (air or speed density systems)
i login to alldata.com and see?
there are 2 engines, a inline 4 and a V6, is MAF.
both engines have the cam timing belt if ignored, both engines
grenade with belt slipped or snapped. dont let that happen.
id never drive any honda , running bad, until the belt is checked 1st.
see why? $3000 new engines are VISA breakers.
OK my easement: (with limited inputs)
too fast hot idle on any MAF engine.
ISC stuck .
ECU in limphome mode, (scan it) and idle controls are shut down on purpose.
air leaks, is not it, if MAF engine, as leaks there cause lean and lean is slow idle (outofcontrol)
tell more, get more.
