Hello , I recently purchased a 2009 Aoord with 116K miles. The car stumbles on occasion when accelerating through 15 to 20 mph . After that it runs smoothly . Any thoughts ??

 

Are your rpm's dropping when you feel these stumbles?

 

Hello , I have not noticed if the rpms drop , I will check in the morning. I checked the DTC codes this morning and no codes registered . Is it possible what I am experiencing is actually in the drivetrain ?? U joints ??

 

what u-joints?

 

Hi, I checked today and the rpms do not appear to drop during the brief stumbling .

 

so your engine isn't stumbling but you feel the car stumbling?

 

That could be a better description

 

I have recently put seafoam in the gas tank , probably one or two tanks ago and Seafoam through the throttle body , thinking that maybe the throttle body flap was sticking. I did not see any difference in the "stumbling"

 

and after that is when you started feeling the stumbling?

 

No, I first noticed the stumbling and in an attempt resolve the problem I did the seafoam treatments

 

inspect your axles, check your transmission fluid.
