Thread: Rattling noise please help

im not sure. others will chime in and can give u a better idea on that.

this is from alldata.

An intermittent may be caused by a poor connection, rubbed through wire insulation or a broken wire inside the insulation. Inspect for the following conditions:

• Misrouted wiring harness. Inspect the ICM harness to ensure that it is not routed near secondary ignition components.
• Malfunctioning Ignition Coil. Remove the ignition coils and inspect the ignition control module and coils for cracks, carbon tracking, or other signs that indicate that the coil secondary circuit is arcing to the ICM or ICM wiring harness. Refer to Ignition Coil(s) Replacement.
• Secondary ignition wire(s) arcing to wiring harness. Inspect secondary ignition wires for carbon tracking or other signs of damage.

IMPORTANT: Remove any debris from the connector surfaces before servicing a component. Inspect the connector gaskets when diagnosing or replacing a component. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion.

• Poor terminal connection. Inspect the harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and faulty terminal to wire connection. Use a corresponding mating terminal to test for proper tension. Refer to Diagrams for diagnosis and repair.
• Damaged harness. Inspect the wiring harness for damage. If the harness inspection does not reveal a problem, observe the display on the scan tool while moving connectors and wiring harnesses related to the sensor. A change in the scan tool display may indicate the location of the fault. Refer to Diagrams for diagnosis and repair.
• Inspect the PCM and the engine grounds for clean and secure connections.

If the DTC is determined to be intermittent, reviewing the Failure Records can be useful in determining when the DTC was last set.
