Installation Tips
Perform OEM Recommended idle relearn procedure. Some applications may require the use of an OBD Scan Tool while others may refer to the Owners Manual.
A relearn of idle values can be forced by disconnecting the negative battery cable for several minutes in order to clear the electronic control module's memory.
Several minutes of idling and highway driving may be necessary to relearn idle values. Electrical loads such as headlights, AC, radio, etc. should be turned off while relearning.
Erratic idle or engine surging after installation of replacement unit may be resolved by putting a load on the engine. If idle evens out after shifting into gear, shift back into park and check idle RPM - perform relearn again if a drivability condition is present.
Clean intake manifold mounting surface and replace Intake Manifold Gasket, if necessary.
Inspect Air Cleaner Intake Hose for cracks and proper sealing - replace or repair with Multi-Purpose Sealant, if necessary.
Check harness for broken wires and wiggle connector to try and reproduce the problem. Replace or clean Connector, if necessary.
Clear all diagnostic trouble codes from vehicle computer prior to idle relearn.
