38 - 0O mod6l3:
NOTE: Before setting the idle speed, check the follow-
ing items:- The MIL has not been reported on.- lgnition timing- Spark plugs
- Air cleaner- PCV system
1. Start the engine. Hold the engine at 3.000 rpm with
no load (in Park or neutral) until the radiator fan
comes on, then let it idle.
Connect a tachometer.
Disconnect the IAC valve 2P connector and the EVAP
purge control solenoid valve 2P connector.

lf the engine stalls, restart the engine with the accel-
erato. pedal slightly depressed. Stabilize the rpm at
1,000, then slowly release the pedal until the engine
idles.
Che€k the idle in no-load conditions: headlights, blow-
er fan, rear defogger, radiator fan, and air conditioner
are not operating,
ldle speed should bo:
480 t 50 rpm {in PErk or noutrall
11-170
lf necessary, adjust the idle speed, by turning the
idle adjusting screw.
After adjusting the idle speed, recheck the ignition
timing (see section 4). lf it is out of spec, go back to
steo 4.tDt.E
6. Turn the ignition switch OFF.
7. Reconnect the 2P connectors to the IAC valve and
the EVAP purge control solenoid valve, then do the
ECM/PCM reset procedure.
8. Restart and idle the engine with no-load conditions
for one minute, then check the idle speed.

NOTE: lf the idle speed increases to 780 t 50 rpm(770 1 50 rpml*, this means the EVAP system is
purging the canister. To stop the purging temporari-
ly, raise the engine speed above 1,000 rpm with the
accelerator pedal, then slowly release the pedal.*: '99 - 00 models
9. Let the engine idle for one minute with the head-
lights (Low) ON, and check the idle speed.

10. Turn the headlights off. Let the engine idle for one
minute with the heater fan switch at Hl and air con-
ditioner on, then check the idle speed.

Fuel Supply System
System Description
The fuel supply system consists of a fuel tank, in-tank
high-pressure fuel pump. PGM-Fl main relay, fuel filter,
fuel pressure regulator, fuel injectors, and fuel delivery
and return lines. This system delivers pressure-regulat-
ed fuel to the fuel injectors and cuts the fuel delivery
when the engine is not running.
Fuel Pressure
Relieving
Before disconnecting fuel pipes or hoses, release pres-
sure from the system by loosening the 12 mm banjo
bolt on the too of the fuel filter.
Do not smoke while working on the fuel system.
Ke€p open flames or sparks away from your work
area,
Be sure to relieve fuel pressure while the ignition
switch is off.
Write down the frequencies for the radio's preset
buttons.
Disconnect the battery negative cable from the bat-
tery negative terminal.
Remove the fuel fill cap.
Use a box end wrench on the 12 mm banjo bolt at
the fuel filter while holding the fuel filter with anoth-
er wrench.
Place a rag or shop towel over the '12 mm banjo bolt.
Slowly loosen the 12 mm banjo bolt one complete
rurn 12 mm BANJoBOLT

SHOP TOWEL
NOTE: Replace the washers whenever the 12 mm
banio bolt is loosened or removed.

Inspection
1, Relieve fuel pressure.
2. Remove the 12 mm banjo bolt on the fuel filter while
holding the fuel filter with another wrench. Attach
the 12 mm fuel pressure adapter bolt and the special
tool.
FUEL PRESSUREREGULATON
FUELPRESSUREGAUGE07406 - 0040001
The illustration shows'97 - 98 models,'99 - 00 models are similar.
Start the engine. Measure the fuel pressure with the
engine idling and the vacuum hose of the fuel pres-
sure regulator disconnected from the fuel pressure
regulator and pinched. lf the engine will not start,
turn the ignition switch on (ll), wait for two seconds,
turn it off, then back on again and read the fuel
pressure.
Pressure should be:'97 - 98 mod€ls:
260 -31O kPa 12.7 - 3.2 kgf/cm,, 38 - 46 psil'99 - 0O models:
270 - 32O kPa Q.A - 3.2 kgf/cm', ifo - /U psil
Reconnect vacuum hose to the fuel pressure regulator.
Prgs3ure should be:'97 - 98 models:
210 - 25O kPa 12.1- 2.6 kgf/cm', 30 - 37 psi)'99 - 00 models:
22O -26iJ kPa 12.2 - 2.7 kgt/cm', 31 - 38 psi)
lf the fuel pressure is not as specified, first check the
fuel pump (see page 11- 183). lf the fuel pump is OK,
check the following:
. lf the fuel pressure is higher than specified,
inspect for:- Pinched or clogged fuel return hose or line.- Faulty fuel pressure regulator (see page 11-
181).
. lf the fuel pressure is lower than specified. inspect
for:- Clogged fuel filter.- Faulty fuel pressure regulator (see page 11-
1811.- Fuel line leakage.

Battery
Test
@M. Battery fluid (eleqtrolyte) contains sulturic acid. lt may couse sevore burns if it gets on your skin or in your eyes. Wearprotective clothing and a fac6 shield.- lf elestrolyte gets on your skin o. clothos, rinse it otf with wator imm€diately.- lf €leqtrolyte gets in your eyes. tlush it out by splashing water in your syes for at least 15 minutes; call a physicianimmediately.
. A battery gives off hydrogon gas. lf ignited, the hydrogen will €xplode and could crack the battery case and splatt€racid on you. Kgop sparks. flamss, and cigarettes away from the batt€ry,. Overcharging will raise the tomperatute of the electrolyte. This may torcs electrolyto to spray out of the battEry vents,Follow the charger manutacturer's instructions, and charge the battery at a proper ral€,
Use either a JCI or Bear ARBST tester, and follow the manufacturer's procedures. lf you don't have one of tnese comput-erized testers, follow this conventional test procedure:
To get accurate results, the temperature ofthe electrolyte must be between 70.F (21.c) and loo"F (38"c).
23-50
lf the case is cracked or the terminals are roose.
replace the batterv.
Check Indicator EYE Color
lf the indicator shows low electrolyte, add distilled
water if possible.
EYE Indicates OK
Test Load Capacity (#1)
. Apply 300 amp load for 15 seconds to remove surfacecharge.. Allow 15 seconds recovery period.. Apply test load (see Test Load Chart).. Record voltage at the end of 15 seconos.
Voltage stays above 9.6
volts; battery is OK.
