Action: Overview

In case of a customer complaint of intermittent high idle on 1995-96 MY 4.0L Sedan Range vehicles within the above VIN range, verify the complaint by checking whether the engine returns to the target idle speed when the throttle is released:

700 rpm in Park/Neutral; 580 rpm * in Reverse or Drive ranges.

* At coolant temperatures less than 86°F (30°C) idle speed +/- 30 rpm; at coolant temperatures greater than 86°F (30°C) idle speed +/- 20 rpm. If a condition of high idle speed is confirmed, check the throttle pedal for obstructions, check that the throttle cable moves freely, and check the throttle cable adjustment (Section 5.1.7 in the XJ6-XJ12 Vehicle Service Manual). If the condition is still present, replace the throttle spring with a stronger spring as described in the appropriate procedure.
