>I really think that is a Nissan thing. I know what you mean though. It >kinda shakes like its gonna stall. But it doesn;t and then it revs a little >then does it again. Nope! Its common with most any modern fuel injected with a fair amount of miles on it. Here why.... If your throttle body was clean and you held it up to a light source you would see a thin sliver of light coming through because there is a little bit of clearance there to let air through to maintain the idle. That small bit of clerance is gone because of carbon build-up over time. When you come to a stop and fully close the throttle you choke off the air to the motor and the motor tries to stall. The ECU gets this info through its various sensors and says "Oh shit! the motor is gonna die!" and tries to compensate by opening up one of the idle management valves. So then the ECU overcompensates and the revs go up too much. The idle management valve is then closed because the ECU knows the idle is now too high. So this might happen a few times before the ECU gets it right and the motor goes back to a steady tick over while you at stop. All you really need is a few basic tools and a can of carb cleaner plus a rag to clean off the carbon. Borrow a tooth brush from your significant other while you are at it and give the TB a good scrub down after you doused it with carb cleaner. A word of warning though, I was doing this one day with one of those long thin red straws that come with WD-40 and the carb cleaner I had bought. As I was shooting the carb cleaner onto the valve the red straw shot off and disappeared into the intake manifold. I spent 4 hours fishing it out with a hook I made with a wire and a 40 minutes job turned into a nitemare. Lesson learned? I NEVER use that stupid red straw anymore.
