Question about 1996 Ford Taurus
1996 Ford Taurus 6 cyl code P0430 am having a hard time starting what could be the issue...turns over but wont fire up except on occasion
P0430 Catalyst System Efficiency below Limit - Bank No 2" How would I fix that without taking it in? P0430 - Catalyst System Efficiency Below Threshold (Bank 2)
you need a scan tool to monitor the upstream and downstream 02 sensors on bank 2 more than likely its the converter. also check for exhaust leaks before converter . Most times the problem is the Downstream O2 sensor is defective.

Tips for a great answer:
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
