Hello,[align=left][/align]I'm looking for a copy of the following TSB[align=left]96234 NOV 96 EGR - Intermittent MIL ON/Multiple DTC's Set [/align]
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 toindicate 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 needof 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.
