Engine Installation
Install the engine in the reverse order of removal.
Reinstall the mount bolts/nuts in the following sequence.
Failure to tollow these procedures may cause excessive
noise and vibration, and reduce bushing life.
1. Install the transmission mount, then tighten the
bolt/nuts on the transmission side. Leave the mount
bolt loose.

a Bleed air trom the cooling system at the bleed bolt
with the heater valve open (see page 10-5).
a Adjust the th.ottle cable (see section 1 1).
a Check the clutch pedal tree play lsee section 12).
a Check that the transmission shifts into gear
smoothlv,
a Adiust the tension of the following drive belts.
Alternator belt {s€e section 23).
P/S pump belt {see section 17).
A/C comoressor belt (see section 22).
a Inspect tor fuel leakage (see section 1 1).
. After assembling fuel line parts, turn on the ig-
nition switch (do not operate th€ starter) so
that the Juel pump operates for approximat€-
lV two seconds and the tuel line pressurizes.
Repeat this operation two or three times and
check for fuel leakage at any point in the fuel
line.

PGM-FI System
System Description
ENGINE CONTROL MODULE (ECMIOUTPUTS
PGM-Fl System
The PGM-Fl system on this model is a sequential multipon fuel injection system,
Fuol Iniector Timing and Duration
The ECM contains memories tor the basic discharge durations at various engine speeds and manifold pressures. Thebasic discharge duration, after being read out from the memory, is turther modilied by signals sent from vanous sensofsto obtain the final discharge duration.
ldle Air Control
ldle Air Control Valve (lAC Vatve)
When the engine is cold, the A/C compressor is on, the transmission is in gear (A/T only) the brake pedal is depressed,the P/S load is high, or the alternalor is charging, the ECM controls current to the IAC Valve to maintain correct idle soeed.
lgnition Timing Controla The ECM contains mamories for basic ignition timing at various engine speeds and manifold pressures. lgnition timingis also adjusted for engine coolant temperature.a A Knock Control System is also used. when detonation is detected by the knock sensof. the ignition timing is retarded(B18Cl engine).
Other Control Functions
1. Starting Control
When the engine is started. the ECM provides a rich mixture by increasing fuel injector duration.2. Fuel Pump Control
a When the ignition switch is initially turned on, the ECM supplies ground to the PGM-Fl main relay that suppliescurrent to the fuel pump tor two seconds to pressurize the tuel system.a When the engine is running, the ECM supplies gfound to the PGM-Fl main relay that supplies current to the fuel pump.a When the engine is not running and the ignition is on, the ECM cuts ground to the PGM-FI main relav which cutscurrent to the fuel pump.

The Heated Oxygen Sensor IHO2S) det€cts th6 oxygon contont in th6 exhaust gas and signals th6 ECM. In operation,
the ECM receiv€s th6 signals trom the sensor and vari€s the duration during which tu6l is iniocted. To stabilize thd sen-aor's output, tho sensor has 8n intarnal heater and the sensor olemant is coatod with a catslyst. The HO2S is installod
