This has gone on for 6 months. The first time when the Engine light was solid, the dealership said the code is P0133 and they replaced the Oxygen Sensor Bank#1. After that, the engine was on and off intermittenly. The second time that it was solid for a while, the dealership had code P0153 and replaced Oxygen Senser bank #2. After that, same intermitten engine light problem. Now, the light was solid. The dealership came up with code P1519 and recommend that the Intake Manifold Runner Control to be replaced. However, they do not have the part and need to order it. So I took the car back. Guess what? the engine light is now off. What should I do? Thanks.
My car is a 1997 Ford Contour LX and at about 78,000 KM
