What I have been reading ,Nissan should have a recall on the intake manifold gasket.My car was not running for a month my mechanic said the problem was the throttle body. I took it to him and told him about the complaint on the intake manifold gasket . He kept it for three days and the problem stop so he couldn't fix it. I have drove it for a week and I feel it idling up again. When I put it in dirve or reverse it moves by itself and I don'y have to push on the accelerator. One year to payoff and this happens that SUCKS.
