The Ford Dealer says that my Intake Runner isn't opening, or at least wasn't, cause the computer had a code in it that showed that happening. I've been noticing that its been hesitating lately, and the acceleration is not right. The dealer says he doesn't want to do anything if while the car isn't exhibiting the behavior. What could I do myself to fix the problem? I was thinking about taking the Intake apart for cleaning sometime soon anyway.
