Hello everyone I’m a new member Ive always wanted to join because every prob I had with my Infiniti I’ll look it up and this site will come up lol, but right now I have a problem with my car basically my car will shut off at slow speeds like when I’m trying to park or easing on the gas at a green light , a week before the car will still turn off but only after a long trip and I observed that it turn off between 1000 and 2000 rpm and I had my spark plugs and 02 sensor replaced yesterday , I’ve been thinking of resetting the ecu I heard people say that could be it should I do that and does anyone have any ideas of what it could be ?

 

Do the rpm's drop or does the car stall when you turn the steering wheel in park? If yes it's probably the power steering pressure sensor.

At city cruising speed if you smash the throttle wide open does it bog and hesitate badly before finally taking off? If yes it's probably a big vacuum leak.

 

Basically at city cruising speed the car works better and no it doesn’t hesitate it’s just litterally when I slow the car down , let’s say I’m first in the lane at a red light , you know that feeling of being the first car at the light you don’t want to hold no one up so when the light turn green you hurry to go ? Basically when I ease on to the gas after the light turns green it’ll make this big lag and jerk feel when I try to ease off but if I was suppose to slam the gas and skip the gap in between 1000 and 2000 rpm it’ll work fine and it’ll get worst after speeding let’s say I rip it down the street and find myself at a red light once the light turn green and I ease on to the gas the car will turn off (all lights still on)

 

Pull and inspect the plugs, check all the vacuum lines for a leak, clean the MAF.
