Hello my name is XXXXX XXXXX I will be more than happy to assist you.
Has the check engine light come on or have you had it scanned to see if there is any codes stored in the PCM?
Lets try this first. Remove the intake tube from the throttle body, and clean the carbon out of the throttle body. See if this helps, if not let me know and we will go from there.
This is something you could do yourself. Here is the instructions.
