so I have a 2012 Nissan Sentra that studders when accelerating.
Before this problem my car wouldn’t drive pass 25mph and would shake if i did.
Changed the spark plugs and bam fixed the problem the car is driving fine until 3 days ago. The stuttering begins.
the stutters happens when I’m accelerating somewhat slowly, if I push on the gas with a heavy foot, the stutters doesn’t happen.
im not sure if I need to change the sparks plugs and get better ones or what can this problem be.
the stutters usually doesn’t happen when I first start the car and drive. It happens when I begin driving about 2-5 minutes in.
took it to auto zone when the check engine light was on and I got this.
most likely soulution
power train system
“replace engine block assembly”
diagnostic trouble codes
power train system p0300 Multiple Misfires Failure
p0300: Cylinder 4 Misfire Detected
thank you
This is a fuel related problem. Are you still running on 10 year old fuel filter, injectors? Have the fuel pump pressure tested.
Remove the air intake hose (between the air filter and the throttle body).
If it's like my 2007, the hose will have cracks and causes stalling/misfires.
