2006 Nissan Maxima Q&A
2006 Nissan Maxima Question: why is it when I start my car it idle loud or maybe I should say high.
If you can remember the carburetor; Cold starts will have the choke engaged causing it to have a higher idle until the engine warms up. Tap the accelerator pedal and the idle would drop. The computer generation has changed that so it will be controlled electronically. If it is louder/higher than normal, have your engine controls tested to find the cause. It is controlled by the ECM/computer. - ProfessorG
