Youtube has videos on how to seafoam. If you unplug your VCT solenoids does the noise go away? Also if you rev to about 1200 rpms or above, does the noise go away?
Today I took apart the Throttle body to clean it, also used MAF cleaner on the MAF sensor. Still has a slight rough idle/tick at idle. I can bump the throttle and im not sure if the sound goes away or the engine noise covers it up. I did unplug the passenger side VCT and didn't get a change, just made it throw a code though. didn't do driver side yet.
I went and bought a motorcraft filter and motorcraft 5w20 and will change the oil soon. Truck runs good driving, its just a little rough at the stop lights, but has not stalled out.
I also noticed I always seem to have water drip from the muffler, looks like it has a few weep holes in it and water drips out of it. Not sure if its just in my head but the noise sounds louder from under the wheel well or underneath as opposed to the engine compartment.
I do have a stethoscope. Im not sure what I am suppose to be hearing though through it?
