7

Engine stalls

After start/at idle

•  Engine stops unexpectedly at idle and/or after start.

(See NO.7 ENGINE STALLS-AFTER START/AT IDLE [MZR-CD 2.2].)

8

Cranks normally but will not start

•  Starter cranks the engine at the normal speed but the engine will not run.

•  Refer to the symptom troubleshooting “NO.7 ENGINE STALLS-AFTER START/AT IDLE” if this symptom appears after the engine stalls.

•  Fuel is in the fuel tank.

•  Battery is in normal condition.

(See NO.8 CRANKS NORMALLY BUT WILL NOT START [MZR-CD 2.2].)

Slow return to idle

•  Engine takes more time than normal to return to idle speed.

•  Engine speed continues at fast idle after warm-up.

(See NO.9 SLOW RETURN TO IDLE [MZR-CD 2.2].)

10

Engine runs rough/rolling idle

•  Engine speed fluctuates between specified idle speed and lower speed and the engine shakes excessively.

•  Idle speed is too slow and the engine shakes excessively.

(See NO.10 ENGINE RUNS ROUGH/ROLLING IDLE [MZR-CD 2.2].)

11

Fast idle/runs on

•  Engine speed continues at fast idle after warm-up.

•  Engine runs after the ignition switch is off.

(See NO.11 FAST IDLE/RUNS ON [MZR-CD 2.2].)

12

Low idle/stalls during deceleration

•  Engine stops unexpectedly at the beginning of deceleration or recovery from deceleration.

(See NO.12 LOW IDLE/STALLS DURING DECELERATION [MZR-CD 2.2].)

13

Engine stalls/quits

Acceleration/cruise

•  Engine stops unexpectedly at beginning of acceleration or during acceleration.

•  Engine stops unexpectedly while cruising.

(See NO.13 ENGINE STALLS/QUITS, ENGINE RUNS ROUGH, MISSES, BUCK/JERK, HESITATION/STUMBLE, SURGES [MZR-CD 2.2].)

•  Engine speed fluctuates during acceleration or cruising.

Misses

Acceleration/cruise

•  Engine misses during acceleration or cruising.

Buck/jerk

•  Vehicle bucks/jerks during acceleration, cruising, or deceleration.

Hesitation/stumble

Acceleration

•  Momentary pause at beginning of acceleration or during acceleration.

Surges

Acceleration/cruise

•  Momentary minor irregularity in engine output.

14

Lack/loss of power

Acceleration/cruise

•  Performance is poor under load (e.g., power down when climbing hills).

(See NO.14 LACK/LOSS OF POWER-ACCELERATION/CRUISE [MZR-CD 2.2].)

15

Knocking/pinging

•  Excessive shrilly knocking sound from engine.

(See NO.15 KNOCKING/PINGING [MZR-CD 2.2].)

16

Poor fuel economy

•  Fuel economy is unsatisfactory.

(See NO.16 POOR FUEL ECONOMY [MZR-CD 2.2].)

17

Emission compliance

•  Fails emissions test.

(See NO.17 EMISSION COMPLIANCE [MZR-CD 2.2].)

18

High oil consumption/leakage

•  Oil consumption is excessive.

(See NO.18 HIGH OIL CONSUMPTION/LEAKAGE [MZR-CD 2.2].)

19

Cooling system concerns

Overheating

•  Engine runs at higher than normal temperature/overheats.

(See NO.19 COOLING SYSTEM CONCERNS-OVERHEATING [MZR-CD 2.2].)

20

Cooling system concerns

Runs cold

•  Engine does not reach normal operating temperature.

(See NO.20 COOLING SYSTEM CONCERNS-RUNS COLD [MZR-CD 2.2].)

21

Excessive black smoke

•  Excessive black smoke is observed in exhaust gas.

(See NO.21 EXCESSIVE BLACK SMOKE [MZR-CD 2.2].)

22

Fuel odor (in engine compartment)

•  Fuel smell or visible leakage.

(See NO.22 FUEL ODOR (IN ENGINE COMPARTMENT) [MZR-CD 2.2].)

23

Engine noise

•  Engine noise from under bonnet.

(See NO.23 ENGINE NOISE [MZR-CD 2.2].)

24

Vibration concerns (engine)

•  Vibration from under bonnet or driveline.

(See NO.24 VIBRATION CONCERNS (ENGINE) [MZR-CD 2.2].)

25

A/C does not work sufficiently

•  A/C compressor magnetic clutch does not engage when A/C switch is turned on.

(See NO.25 A/C DOES NOT WORK SUFFICIENTLY [MZR-CD 2.2].)

26

A/C always on or A/C compressor runs continuously
