Question about 2003 Nissan Altima
Is the check engine light on? If it is, take the car to an autoparts store and have them scan the car's computer for any fault codes that are stored there. Most parts stores will perform the scan at no charge. Getting the codes will help narrow down the cause. There are a few things that could cause these symptoms and it's best not to speculate if you don't have to. Hope this helped and best wishes.

The throttle body has carbon buildup around the throttle plate.
thats the plate that opens and closes with the gas pedal.
open up the intake system to the throttle plate and use carb cleaner in a spray can to spray in and clean around with a very clean cloth rag.
DO NOT DROP NOTHING IN THE INTAKE SYSTEM.its ok to drip some spray in there but use the rag around your two fingers to rub that stuff loose.and dont let anything else get in there.like chewing gum or beer or chips or stuff like that.
at an idle position the buildup closes more of the gap at this plate at idle position.and the computer is trying to compesate when you put it in gear.
spray out the thorrotle body and use super unlead to prevent this from happening again.
you do not want unburt fuel coating the inside of the engine caking up all the computers sensors and causing problems like this.
super keeps it all clean.no no mid grade.
let me know
