it does
Customer reply replied 6 months ago
Hesitates too
Thank you. If it is intermittent then chances are it is a carbon issue or simply dirty injectors. I usually run a can of Seafoam through the intake to see if it helps and clean the injectors. Also, if the wrong spark plugs were used that can cause it also.

What do you think of running CRC thru the throttle body
That tends to work well also.
