Conduct power balance test. CONSULT method: Start engine. Conduct "POWER BALANCE" test with "ACTIVE TEST" showing on display. Test must be finished as quickly as possible. Do not conduct test while vehicle is being driven. Check to ensure idle speed momentarily decreases while testing each cylinder. No-tool method: Start engine. Check to ensure idle speed momentarily decreases when each injector connector is removed from cylinder.
N.G.
Go to 9 (fuel pressure check on this procedure)

Check injectors. Stop engine. Remove distributor. (Do not remove crank angle sensor harness connector.) Remove power transistor connector. Turn ignition switch to "ON". Check to ensure each injector emits hissing sound when crankshaft is hand-rotated. Display shows an erratic indication during self-diagnosis and does not show abnormalities.
N.G.
Check injectors and circuits. Refer to "Injector". (See page EF&EC-153).

Check compression pressure. Standard value: 1,324 kPa (13.24 bar, 13.5 kg/cm², 192 psi)/350 rpm. Limit value: 1,128 kPa (11.28 bar, 11.5 kg/cm², 164 psi)/350 rpm. Pressure difference tolerance among cylinders: 98 kPa (0.98 bar, 1.0 kg/cm², 14 psi)/350 rpm
N.G.
Check piston, piston rings, valves, valve seats and cylinder head gasket.
