I have an intermittent problem with low throttle stumbling and hesitation. No malfunction light and no codes according to the local auto parts store.

Any input would be greatly appreciated!

 

Forgot tpo mention, the car is completely stock. 62k miles automatic transmission...

 

My 2007 does that. No trouble codes. Only happens when the vehicle has not reached normal operating temp. I think this is normal for our cars. Only happens on very light throttle and when cold.

I tried the throttle body cleaning and I think this helped as I notice it is happening less often. Maybe one day Infiniti will come up with a reflash to fix this annoyance.

 

I'm having the problem when the car is warmed up.

A few months ago the car died after going through a car wash. I'm wondering if the problems are related...

 

Try cleaning your throttle body.

It makes it difficult to diagnose when it doesn't spit out any trouble codes to aid in the diagnosis.

 

Sorry for not getting back to you. I cleaned the throttle body and MF sensor, reset the ECU and TPS.

End result? Hesitation is allll gone. Much appreciated
