Hey my names lacy(guy) new to the foum just picked up a 96 ranger 4x4 4.0 5speed
im having the following symptoms
dtc1151 and 1443
when starting cold
Random high idles around 2k 2.5k
the idle sound like a vaccum leak but i check all hoses. I no i had a bad hose going to the egr vac solenoid and a bad solennoid. replaced helped but not fixed.
no i hear a nice sucking from under the upper intake all hoses looked to be alright i wiggle etc.
-When i snap the throttle you can hear it make a shoooop sucking sound. To me sounds like its in the back middle ish is this a normal sound?
What you think upper inake cracked? (its plastic)
Could a valve cover do this?
