I have a 2003 Ford Expedition, with the 4.6 V8. It started to idles rough and stall after decelerating, it also threw a P2196 code. It has thrown this code before and it turned out that the PCV hose behind the throttle body had a hole in it. So that was the first place I looked this time, but there were no leaks or hole. I leak checked the rest of the vacuum hoses, but found no leaks. I begining to think it's the IAC. Any suggestion?
have the same problem?
