Slight popping noise through intake 2005 Ford Taurus
2005 Ford Taurus OHV engine. Anyone run across this? You can hear a slight random popping sound through the intake at idle. No DTC's. I did a quick check for vacuum leaks with some brake cleaner, nothing found. Seems to run ok, although it does have a slightly rough idle on cold start ups at times.
Those still a 3.0 if so it could be the cam pos. sensor looks like a half of a distributor in the engine valley on driver side.
Yeah, still a 3.0. That was my first thought, I know how common the cam sensor/synchronizer problems are on these. I've changed a few. Usually for the squealing or cutting out problem though. I would think it would throw a DTC though if the cam sensor is dropping out signal though.
I had one that never threw a code could watch the scope and the only thing that feel off was the fuel pump I was about to change it and decided to try the sensor cause fuel pupms on those are rare changed the sensor and fixed it.
