No.	TROUBLESHOOTING ITEM			DESCRIPTION
1	Melting of main or other fuses			—
2	Will not crank			Starter does not work.
3	Hard to start/long crank/erratic start/erratic crank			The starter cranks the engine at normal speed but the engine requires excessive cranking time before starting.
4	Engine stalls.	After start/at idle		The engine stops unexpectedly at idle and/or after starting.
5	Cranks normally but will not start			The starter cranks the engine at normal speed but the engine will not run.
6	Slow return to idle/fast idle			The engine takes more time than normal to return to idle speed. Engine speed continues at fast idle after warm-up.
7	Engine runs rough/rolling idle			The engine speed fluctuates between the specified idle speed and a lower speed, and the engine shakes excessively. Idle speed is too slow and the engine shakes excessively.
8	Runs on			Engine runs after engine switch is turned to the off position.
9	Engine stalls/quits.	Acceleration/cruise		Engine stops unexpectedly at the beginning of acceleration, during acceleration or while cruising.
	Engine runs rough.	Acceleration/cruise		Engine speed fluctuates during acceleration or cruising.
	Misses	Acceleration/cruise		Engine misses during acceleration or cruising.
	Buck/jerk	Acceleration/cruise/ deceleration		Vehicle bucks/jerks during acceleration, cruising, or deceleration.
	Hesitation/stumble	Acceleration		Momentary pause at the beginning of acceleration or during acceleration.
	Surges	Acceleration/cruise		Momentary minor irregularity in engine the output.

11	Poor fuel economy			Fuel economy is unsatisfactory.
12	High oil consumption/leakage			Oil consumption is excessive.
13	Cooling system concerns		Overheating	The engine runs at higher than normal temperature/overheats.
14	Cooling system concerns		Runs cold	Engine does not reach normal operating temperature.
15	Excessive black smoke			Excessive black smoke is observed in the exhaust gas.
16	Engine noise			Engine noise from under the hood.
17	Vibration concerns (engine)			Vibration from under the hood or drive line.
18	A/C does not work sufficiently.			The A/C compressor magnetic clutch does not engage when the A/C switch is turned on.
19	A/C is always on or A/C compressor runs continuously.			The A/C compressor magnetic clutch does not disengage.
20	Intermittent concerns			Symptom occurs randomly and is difficult to diagnose.
21	Constant voltage			Incorrect constant voltage.
