Can you supply us with the Code number? Which Filter do you have? if you have K&N filter or similiar oil type filter you may just need to clean the MAS sensor with Carb&choke cleaner. Some people put on too much oil onto the filter and it sprays onto the sensor when driving. that or they do not wait until the filter completely dries.

Code P101, and it prob. needs cleaning.
