i would take your car to advance auto or autozone and have a scan tool put on your car as this is the easy way to find the problem.your problem could be many thins from a bad o2 sensor to a bad sensor.without seeing the car its hard to say from here.thats why the scan tool,and these two places do not charge you for this service,a garage will charge 100 dollars or more.hope this helps.
