Once you have the codes, you can look them up on the web. Just do a search ' 94 Lincoln town car code.....' Just plug in the code(s) number.

sounds like you may have some linkage problems

Broken throttle cable ?

this is a code for a rear o2 sensor. first try to replace the fuel filter and reset code. if you have a OBD 2 code reader 30.00 wal- mart or your local parts store. if that didnt fix it replace the heated O 2 sensor it is behind the catlytic converter there is only one. its around 148.00 for it

There should be no difference in using an OEM or aftermarket cat to the O2 sensors-as long as it fits with no leaks, it will do exactly what an OEM cat would do, with a significant savings. When the pipes are dropped behind the cats, inspect for 'clogging'-although it does happen, your cats behind your 4.6 are not as prone to breaking up as the earlier generations of catalytic converters, so look yourself for proof that they are damaged. If you do replace the cats, the rear sensors only monitor the cats thenselves they do NOT affect the way the engine runs at all. You are being sold a bill of goods in my opinion.
