remove upper intake plenum
you have to remve the intake manifold
The IAC valve is mounted on the upper intake plenum (manifold)
intake nut 89lb .in stud 106.lb.in plenum is 25nm
Correct torque on 2000 model : 18 Ft. lbs.- upper intake manifold [ plenum ].
The car engine air filter is below the intake plenum. remove the plenum to the throttle body and underneath to the actual air filter housing. Pull back the three quick clips and there it is.
under top plenum on 3.1 engine at intake manifold.
under the intake plenum for the fuel injection. Not an easy job to do for the back yard mechanic.
ECM is located on drivers side, below the base of the windshield underneath the plenum. You have to remove plenum panel for access.
its on the right side of the throttle body where the plenum hose goes into the intake manifold
You must label and disconnect all plug wires and other wires in the way of getting to the intake manifold, valve covers, and head/heads. Then you disconnect the air intake/plenum, and intake manifold. Then remove the valve covers. Then remove the manifolds and the head. Do not attempt this without a Chiltons or Haynes book/detailed instructions, unless you are a certified mechanic.
