1994 - 3.0L 2WD
Just replaced rotors, Calipers, and pads. Bleed brakes - all is well there, then moved on to the Valve Cover Gaskets and the upper Intake Gasket.
That went well with minimal surprises, the one surprise was that there were 2 gaskets on the upper intake. My purchased replacement only had 1, so that is all she got back. This is only suppose to have a single gasket yes?
Valve covers went fine as well, my first time doing an intake and valve covers so I went slow, and methodically, taking several pictures of vacuum lines prior to ripping them apart and moving things. Came in handy when reassembling, that is for sure.
While I had it apart and had easy enough access, I swapped the plugs too. I failed to research here, so I did not use the motocraft SP-500's, instead going with NGK from autozone.
After reassembly, I had a really rough idle, sounded like it was about to stall and engine was bouncing around. She ran smooth prior to my "fixing", so that was a bit troubling. Initially I thought I missed a vacuum line or had one not seated properly. I looked over them again, verified with my photo's and then sprayed BrakeKleen (was out of carb cleaner) at all the connections...... idle remained unchanged so no vacuum leaks.
Had it sit there a few, then unplugged the IAS, and she died rather quickly. PLugged it back it, cranked her up, and turned the idle screw up until she no longer was jumping around and sounding like hell, then unplugged the IAS again, idle fell lower, and started bouncing around all rough again, plugged the IAS back in and idle raised and smoothed out.
I did NOT touch the idle screw upon my work dismantling the intake, is it common for that to get "shifted" during that process? My truck does NOT have a tach so I am unsure of the RPM's. Need to get one installed so I can check that idle speed out.
Thanks for any input on idle screw setting getting moved during intake removal.
