Could really use some help

BOOGING and not misfiring?????
GooD 12s,. this ecu has no misfire monitors until 1996. usa laws, invented this OBD2.

if i could buy 10 of these cars, 24 year old cars.
I could in 1 day, show 10 serious problems with it. every one ive seen are full of problems, folks just drive them. and they stack up.
if you remove any sensor key on , it will store and error for senor pulled, that is its job, its called a monitor (a nanny)
all cars do that, even new.

step 2 is , what I asked before
warm, its not suppose to run warm its must be hot, hot is 180f, the top hose on rad, will get so hot, you cant keep a hand on it.
(assumes non coal miner hands)
it must reach 180 and and hold there. do not ever use a 160 thermostat in any EFI cars.

so is it fully hot.??? the engine, if yes then the IAC closes, and RPM go to normal. (the iAC test is tricky, because the air path is hidden)

First learn rule one on 8v TBI G16a engines , all air leaks results in fast idle. with FULL POWER.!!!
so does (AC on, and Power steering overload call up 1000 rpm)

there are 4 air supplies. and more if things leak like hoses.
1: THE TV throttle plate is 99.9% closed, parked at idle, if not the throttle cable is bad, set wrong or the throttle bore is gunked up blocking the TV open.
just press on it, does RPM drop, bingo, TV failure. TV means Throttle valve.
2: the idle bleed screw.
3: the ISC electric idle speed controls valve. PCM controlls this. and forces 800 rpm,. ECU hard rules, not i FAST IDLE UP MODE.
4: the IAC, is in the base of the TB, throttle body and is 100% thermal, if water temps do not cross past 155F the VALVE leaks air, as designed to do.

that is besides vacuum leaks , many. possible

so is water temp at 180f, this is just step one, in the long process simple tests.

Ever do a full tune up with the timing belt.
if not it slips. and then spark timing goes way off ,and cylinder compression can drop to 80psi from 170. oldest story on G16, all do that everyone, ignoring the belt.

i use my timing light, and go wow, timing is way off, belt slipped, (timing freeze jumper inserted in DLC for sure)

many off these cars with no cooling system flush, the IAC hose packs in gunk.
this blocks it
and the IAC sticks open forever. the water path through the IAC must flow and must be 180F or more.
this is the cold engine, fast idle valve,. so if not hot, it stay on. and races super fast.
it can also fail. it can be tested in a pan of hot water, easy. (TB removed)

so is it 180f? hot fully hot engine?
