My automatic 2.4 Altima fails at low revolutions, it behaves as if it wants to stall, with the brake it does the same and adds an annoying vibration, the same in reverse. It works normally while driving, it only does this at low revolutions. I already changed the spark plugs, checked the injectors, replaced the engine support and I can't fix it.

Hi , i've replaced the in tank fuel pump and the high pressure fuel pump. As well clean the injectors and replaced the crank sensor yet still sometimes the vehicle will take few seconds to start up and sometimes it will just start up immediately, with no any issues. I've hooked up a scanner and did not find any codes ?!

I have Nissan Altima 2001 model
The problem is I have change my starter,alternator and injectors but yet still my car gives a strange sound,when is park and you start the car it will start and give you a good sound but when you change the gear to drive then it begun to give you a sound like gun shot and the car wont move. Please I need solution
