Worn, damaged, or incorrectly installed crankshaft breaker gear. A worn or damaged crankshaft breaker gear can cause a variety of symptoms depending on the severity and location of the wear or damage. Electronic communication systems, direct ignition system (DIS) or the ignition coil on each cylinder, with significant damage to the chopper gear ring, may show intermittent loss of crankshaft position, loss of signal, and then restoration of crankshaft position. Electronic communication systems, direct ignition system (DIS) or the ignition coil on each cylinder, with minor damage to the breaker gear ring, may show no misfiring and loss of the specified position of the crankshaft. Mechanically coupled systems, a high voltage switch, if the breaker gear ring is significantly damaged, can cause additional impulses, affect the fuel supply and the ignition spark supply.	Check crankshaft position sensor. Carefully inspect the crankshaft breaker gear. Check crankshaft. Repair or replace damaged components as necessary.

Worn, damaged or loose timing chain and sprockets.	Carefully inspect the timing chain and sprockets. Repair or replace damaged components as necessary.
Worn, damaged or incorrectly installed piston. Pistons must be installed properly with the marking or indentation on the top surface of the piston facing the front of the engine; The piston pins must be centered in the connecting rod pin hole. Oil consumption may or may not cause engine misfiring.	Check spark plugs. Cm. "Checking the spark plug" in this section. Check engine compression. See "Compression pressure test"in this section. Carefully inspect the cylinder bores. Check pistons. Check piston pins. Check the cranks. Repair or replace damaged components as necessary.

Initial misfire with abnormal interior noises at the bottom of the engine

Cause	elimination
Worn, damaged, or improperly installed accessory drive belt. It has cracks, bumps, or missing segments. A misfire DTC can occur without the actual conditions causing the misfire.	Carefully inspect the components of the accessory drive system. Repair or replace damaged components as necessary. See Part 1C2, "The mechanical part of the engine is HFV6 3.2L.
Worn, damaged, or incorrectly installed accessory drive system components. A misfire DTC can occur without the actual conditions causing the misfire.	Carefully inspect the components of the accessory drive system. Repair or replace damaged components as necessary. See Part 1C2, "The mechanical part of the engine is HFV6 3.2L.
Worn, damaged, incorrectly installed or insufficiently secured crankshaft pulley. A misfire code may appear without the actual conditions causing the misfire.	Check the crankshaft pulley. Repair or replace damaged components as necessary. See Part 1C2, "The mechanical part of the engine is HFV6 3.2L.
Worn, damaged, incorrectly installed or insufficiently secured engine flywheel. A misfire code may appear without the actual conditions causing the misfire.	Check engine flywheel. Repair or replace damaged components as necessary. See Part 1C2, "The mechanical part of the engine is HFV6 3.2L.
Worn, damaged or incorrectly installed piston. Pistons must be installed properly with the marking or indentation on the top surface of the piston facing the front of the engine; The piston pins must be centered in the connecting rod pin hole. Oil consumption may or may not cause engine misfiring.	Check spark plugs. See Part 1A3, Basic data of the HFV6 3.2L engine. Check engine compression. See "Compression pressure test"in this section. Carefully inspect the cylinder bores. Check pistons. Check piston pins. Check the cranks. Repair or replace damaged components as necessary. See Part 1C2, "The mechanical part of the engine is HFV6 3.2L.
