QuestionI have an 02 grand caravan sport with a 3.3 v6.. it has a random stuttering problem at idle or any engine speed, moving or stopped. while accelerating, it sounds like it is spitting up through the intake. we had a vacume emissions leak which a new glas cap fixed. i used a code reader to turn off the check engine light and it has stayed off for several days. however the spitting is still there. sometimes it is very apparent, other times it could be mistaken for a bump in the road. i believe it to be something that is not tied to the check engine notifications since the light is not coming back on.
do you have any advice?
