2008 Infiniti G35 ProblemsErratic or High Idle After Cleaning Throttle Body
The throttle body for the Infiniti G35 is known for carbon buildup, and requires regular, light cleaning to maintain peak performance. After cleaning the throttle body, many owners notice a very high idle, erratic (bouncing) idle, and unpredictable power surging.
The cause is normal ECU adaptation: When the throttle body builds up carbon, the rate of airflow is slightly decreased. The vehicles computer reads this decrease in air volume, and adjusts the throttle body settings to maintain the proper engine idle speed. When the carbon is cleaned out, the ECU now registers too much air, and cannot adjust back to the original settings. While it is trying to change settings, the idle will bounce from low to high, and the car will surge forward at times.
It has been recommended to simply wipe inside the throttle body every 12,000 miles, and never to touch the flap inside. Also, the cleaning procedure may be best left to a qualified technician.
The solution can be as simple as disconnecting the battery for at least an hour, having the dealer reset the computer, or, in extreme cases, replace the throttle bodies.
The crankshaft angle sensor or the camshaft position sensor can fail and cause loss of engine power, an engine that cuts out, and other drivability problems. This will cause the Check Engine Light to illuminate. Certain models have been involved in a recall to replace the camshaft and crankshaft sensors.

2008 Infiniti G35 RecallsPassenger Air Bag May Not Deploy
This recall affects certain vehicles equipped Occupant Classification System (OCS) control units manufactured by Continental Automotive Systems. A varistor in the OCS control unit may have been manufactured out of specification. Under certain conditions, this could interupt the signal between the OCS and the air bag control unit (ACU), causing the passenger air bag to be suppressed in an accident. If the air bag does not deploy when needed in a crash, the risk of injury is increased. Dealers will test the signal between the OCS and ACU with a special tool to verify proper function. The seat cushion containing the OCS hardware will be replaced as necessary. The recall began November 4, 2008.
