G35X V36 2008 IDLE PROBLEM

[dohio69]

hi guys, got the car parked for 1 year, just bought a new battery, but now the car runs between 1400 and 1800rpm with oscilation on P or N, but when a put D the idle speed gets steady below those range. Whats the problem??? please help

PS: the tank was full with premiun gas all that year

Kinda sounds liek it's choking out, I honestly don't know if the G uses an iacv if so clean it, if not I'd clean the TB.

Yup clean throttle body... check CPS as well... Bank 2 gets gunked up and makes idle funny.

oh almost forgot there is no IACV... but you can try the relearn after cleaning the CPS and TB... should fix ur probs.
