97 Sidekick Sport 1.8L - CUTS OUT AT 1/4 THROTTLE
MORE SURE
BE HAPPY IS NOT THROTTLE BY WIRE(TBW), AND $1500 PARTS TO FIX IT.? (look ma, no cable now,, and no lawsuits)

ok, you have 4 advantages here. at least, not TBW above, is one but counting that..
1: cables one can and sees all 3 cables (2 you) are slack and not holding MR TV brass plate open
2: the plunger, is a thermal iAC, (small) and most NOT hold open Mr, TV at any time hot. ever. or its bad.
The "A" dimension is 1.048 to 1.078" @ 25deg C or 77F and fully retracts off cam at 126 to 154deg F. spec inbook, (180f is always fully retrated.
one can look at the TB/Tv STOPS, TO SEE THE TV IS 100% CLOSED AT ANY TIME HOT, AND END THE WONDER MENT OF ALL THIS.

BUT NOT THIS. THIS IS AN ELECTRIC AIR VALVE (IDLE CONTROLLER)
3: the iSC can be removed and cleaned,its all by its self there.

in most cases, vacuum leaks,cause lean and too SLOW idle. (vacuum leaks can buy pass the MAF)
or stalls
BUt there is this nice exception to rules. like that
its ,
PCM in limphome, mode, and rich as piggy
then one gets failure 2, vacuum leaks
so rich fuse, + leaks equals, RACING.
pinching hoses finds them(most not all, seen even egr gaskets missing etc.


this is a serial process, and where we go depends on evidence and testing.

#4 last and not least the TV can be seen by humans, not on G16b running
on your cool engine, the TB has an on board, MAF
that means you can run engine, and look inside and see, if the TV is open, ACID test way, see? the TV is 99.9% closed,
the 0.1% Prevents the TV plate from jamming in the bore, and gouging it out each time you lift your right foot. all bad bad that.

even in limp home a brake vacuum booster could cause RACING (means screaming idle) and dangerous, with a/t traNS AND LATE TEEN DRIVERS.
ever seeN the 1996+ rules on limp"(AT AND OF THIS PAGE)

btw
#2 here is PLUNGER

my 1.8L idle page covers all this tuff

last limp

MAF = P0102/103
IAT = P0112/113
ECT = P0117/118
TPS = P112/123
VSS1 = P0500 ( speedo vss) Vehicle Speed sensor = VSS
TR = P0705 (A/T Range shifter output in conflict)
VSS2 = P0720 ( 4sp Vss tail speed sensor dead)
SS#1 = P0753 (shift solenoid 1 bad)
SS#2 = P0758 (shift solenoid 2 bad)
TCC = P0743 (torque converter clutch malf)


the full ist is in he SM for 1.8,that I dont have.
this is pure software rules. best is to have no DTCs, and win the war.


best post
in the end, the poor human must make the computer brain happy.!
