Throttle body cleaning is good and I do it every 2 years in all the cars, except the M35 and 03Q45. Nissan/Infiniti does not recommend cleaning of "drive-by-wire throttle" as it can cause Idle Speed Control problems which may not be covered by warranty. The 2nd time I cleaned the TB of our 03Q, I had P0505 which I can't reset. The dealership spent several hours diagnosing it, doing leak checks and re-programming of the ECU to no avail. The TB was eventually replaced. Fortunately for me, the car was still under warranty and Beshoff Infiniti-San Jose did everything - parts and labor, free of charge.
