A diagnostic test showed that I need to remove and replace the intake manifold runner control. Is that necessary?
I want to make sure the repair that has been suggested is necessary. My check engine light went on but I haven't been experiencing any problems and the car is running like normal.
In order for us to properly answer your question we need the 4 digit code that you got when you had the test done. Post back here. Hard to say you need to replace a sensor or not from where I'm sitting.
