i noticed lately that my car has a very slight hesitation when going from a stop. this ONLY happens in the morning (after not using the car all night) and when i get to a stop light. it only happens once. it's a slight hesitation when i hit the gas.. almost feels like the car is going to stall, but it doesn't.

anyone else ever experience this?

 

whre are you located? is in a cold area? Also how long has this problem lasted? I know that one time I forgot to properly screw in my gas lid so before the CEL went on there as some hesitation, so possibly if this problem just came up fill up again to the top and then close your gas cap shut.

I have this same problem too...quite regularly I might add. Not sure what the deal is, but as you mentioned...once the car warms up it goes away.

 

UPDATE:

after getting my battery changed, i don't notice this problem anymore.

psychdaddy, how old is your battery?

 

This was caused by a battery?!? I would have never guessed

 

Yeah i doubt this would be the battery....
Its a good idea too let your car warm up for a while...
Reason if you notice it doesn't once i means it happens right when you attend a stop.

 

The OP did mention that it only happens in the morning before the car has been driven... how old is the battery?

My guess is, the battery isn't holding a good charge and coupling that with cold mornings, the charge is weaker than when it is warmed up. Cold isn't good for batteries anyway ...

The puzzling part is, I was always under the assumption once the car has been turned on, the battery doesn't do anything at all and does not have further use.... guess it does and I was mistaken

 

Mine does it. Even when warmed up. It's just part of the lurchy charm that the Infiniti becomes.

 

I've noticed this in my Murano here an there...

 

Mine does it every single day before the engine/transmission reaches normal operating temperature. It happens when I roll up to a stop sign where the transmission has to downshift to 1st to get going agan. When I go to accelerate, the car nose dives for a split second and gets going again. It always throws my head forward some if I don't prepare for it.

 

mine does this as well when cold....when i leave my dead end road and come to a stop and then hit the gas pretty quick i get a big hesitation..but that's the only time it does it in my trip...weird

 

Dirty TB?

 

forgot to mention that i also changed my serpentine belt along with changing the battery. i don't know which to attribute it to, but it did seem to go away after i changed both mentioned items.

RedBaron, i cleaned my TB last year so i don't think that's was the problem.

 

I doubt it has anything to do with the battery, throttle body, or the serpentine belt. If I had to guess, I'd first start with the transmission controls (either hydraulic or electronic i.e. programming), then venture to say it may have something to do with the ecu programming of fuel trims or timing at a particular load within a certain engine/tranny operating temperature (in this case below normal operating temperature).
Personally, it's one of those small quirks that I find pretty tolerable knowing that this occurs in most of our cars.

 

I agree.
