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 sensorHard to start - 2_bing.gif is defective.

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

I have a 1996 Ford Taurus GL, and the temperature gauge fluctuates up and down and i replaced the water pump replaced and all that other stuff, and than the check engine light is on and I have disconnected...

P0420 and P0430 are catalytic converter codes indicating that the converter isn't working properly. Temp gauge fluctuating can be caused by a bad thermostat, bad temp sensor, bad wiring harness to the sensor. Also check for air in the cooling system. Read the post below for more information on the catalytic converter issues.

Drive 5 miles and starts up fine, drive 30 miles and wont restart

Sounds like a fuel pump overheating. Drive until it wont start then check the fuel pressure. If no gauge when it wont start try some starting fluid. You should also check your fuel pump relay.

My Ford Taurus 2001 Suddenly stopped starting. The ignition sounds fine, Turns over, but nothing is catching. Battery is fine, gas level is fine, no check engine light.I thought maybe it just wouldn't...

Some fords if you slam the trunk lid too hard, it pops the fuel shutoff relay in the trunk area. It is like a circuit breaker you just push the button to reset it. Or you copuld have a sensor under the hood went bad(crankshaft position sensor, camshaft position sensor, mass air flow sensor).
I would start by calling the ford dealership to verify the whereabouts of the fuel shutoff relay, and start there. I had a few late 80's taurus'sand they were on the drivers side in the trunk behind a plastic panel(ford may have relocated them since), and i ran into this problem with them. I learned the hard way, the first time it happened to me I went and bought another taurus and started stripping the first one for parts, when a friend showed me that switch, I pushed it a lo and behold the darn thing started. I was mad and happy at the same time.

You are mis fireing on cyl 1 and 3 if you replaced plugs and wires and coil this is going to be a fuel injector issue or valve issue. See if you can swap the injectors with known good cyl. and see if it changes. Or have a shop do a fuel injector service on it to see if it helps. It may be to late for the fuel injector service.

You really have to think a bit about when those sometimes are. Is it only when the engine is already warmed up? Is it only when the engine is cold? If you have a tach on the dash, what is the real high idle speed of the engine? How many rpms? Does the transmission shift hard or smoothly?
