Performance Issues.
Hey all, long time member here, but haven't needed to post in a while since the old Ford has been serving us well.
Lately, when slowing down to a stop, or very slow speeds, the intake ducts make a very loud moan. It sounds like a muted horn really. Sometimes, I can put it in park, and it'll be making the noise. Open the hood, and it feels like it is coming from the plastic intake tube. When it does this, the motor likely stalls out, and needs to be restarted.
Another issue, we cruise with it at roughly 100 kph. It works good, that 4.0 has gobs of power, but when cruising, sometimes it will very randomly work bad, just have a misfire hissy fit! It doesn't affect the cruising, but it just works funny.
Its a 1997 Ford Aerostar with the 4.0 OHV, and the E- 4wd with the Dana TC28 transfer case.

Do a full tune up with OEM grade ignition parts (Motorcraft, Autolite, NGK, no other brands), clean the MAF sensor with CRC MAF Sensor cleaner, new air filter, and replace the fuel filter with an OEM Grade (Motorcraft, Wix, Purolator), clean the throttle body and IAC motor with throttle body cleaner.
