Looking for the firing order for 1997 nissan hardbody pickup ka24e engine

NO control told or miles on engine (KM) odometer.
what is a hardbody, a Pickup , not in USA are you? no country told

SO YOU POST TO THE BLIND AND DEAF THIS.?
why not ask a live hands on service tech to check it out and not blow up a still good engine, why NOT?

yes the pickup truck hardbody means double wall bed.
my guess engine is 2.4L 4-cylinder KA24E
a specific engine that.
KA24DE 2003.
the DOHC<? twin cam is buckets over valves cam direct via CHAIN those are bucket lifters only, and only make noise if it sucks a valve.
ever, oKay
the chains can fail 200k miles, or KM equiv.
if you allow most DOHC chains or belts to fail the engine valves are bent over and worse.
so learn to get that checked out and not ask the deaf ever.
do not delay , IMO ID not drive, it at all , or go to the mech shop now. no delays.

a pickup , hardbody means pickup bed walls are double walled, only. aka D21 pickup?
USA car, " ? not told engine there, lots of engine world wide, but ours is but 1. USA>
2.4L? Iine 4 cylinder.
guess #1 real name of real engine by them..
2.4 L KA24E I4 (1990-1997)
in the USA the EPA banned all those screws.
by law. the idle speed is fully computer controlled.
all USA cars, idle speed is regulator fast by the PCM
using device called IAC/ISC/ has 2 wire IAC.
IAC is bolted to TB lower side base, 2 wires.

if Idle hot is not at 800RPM and not regulating there are 3 common causes.

1. ISC is stuck (needs cleaning)
2. vacuum leaks, makes the ISC useless. (over-ranged) cracked vacuum lines and more.
3. thermostat bad,engine never gets to 180f up. temp.

the screw here is factor OEM calibration
called the never touch screw.

yellow circled. this screw sets idle duty cycle to 50%
as covered in the real service manual
seem carb guys monkey this screw and IAC and PCM go nuts.
if was messed with by others I set mine to
0.001" gap TV to bore inside the TB bore'/
