Hi Scotty the best Mechanic in the world. I have a 2004 Nissan maxima se i clean the throttle body with tb cleaner. The car actually is running better. The only problem is after i finish cleaning it my service light came on. I did push back the Tb with my fingers did this cause my service light to come on. I got the code reset two times and it came right back. What do you think the problem could be.
