Hello,

 

I'm looking for a copy of the following TSB

96234 NOV 96    EGR - Intermittent MIL ON/Multiple DTC's Set

 
I'm working on my daughters 94 Crown Vic with the 4.6 PI engine, and its returning a 332 (insufficient EGR flow) code.  All of the checks that I've done appear to indicate that the EGR passages are clogged.  I'm trying to get the car running better before my daughter sells it (dirt cheap) to a single Mother friend of hers.  They work as nurses together, and she is in desperate need of reliable transportation  I don't have a manuals for this vehilcle, and so I'm trying to work through this problem doing research on the net. 
 
Any help would be appreciated.

EGR - clean the passages and add a new valve. Carb cleaner might help some on a q-tip unless you have a small wire tube brush.

3. If engine rpm does not change when performing test "EGR3" of Step 2, and the EGR valve checks good, check the EGR passage between the intake manifold and the throttle body for carbon blockage (Figure 1).
