Check Engine Light?

Engine Cooling problem
1997 Ford F150 V8 All Wheel Drive Manual

just changed my coolant and ran the truck, after an 15 mins the check engine light came on. Help!

Took it to auto zone their diagnosis was random cylinder misfire, so must have just been coincidence.

I was driving last week and my truck overheated. It went into the mode where it turns off four of the cyllinders. I turned the truck off, restarted and everything was fine. I started having fluctuations in the temperature so I replaced the thermostat and the problem went away. Shortly after the checkengine light came on. Today I found as I was driving the temp gage never moved and the heater neverturned on. The fact was there was no water in the radiator. I filled it up and drove to work. Ran terrible and a couple times the check light started flashing. I know I need to diagnose the computer, but I was wondering what might cause this. Will the O2 sensor cause the engine to burn water? I havent seen any leaks. Thanks for any help.

My check engine light came on and I took it to

auto Zone where they told me that I had a Code 88 which is: Catalyst efficiency low-bank 2. What does this mean and how do I fix it?

The Vin # on the F-150 is 1FTDX1761VNA16439

While driving down the road the check engine light on my 1997 ford f150 came on. The engine is still running the same as usual. What would cause this problem?

Truck has had three sets of plug wires and plugs (best wires the ford place had and the best platinum plugs), new fuel filter and one new coil pack installed in the past year. Each time the service engine light would go off and stay off a few days before coming back on. After the light comes on the truck starts to miss at idle and while in overdrive and the truck is under a load such as pulling a hill at cruising speed. If truck is run for a couple of weeks the miss gets worse(runs like it is hitting on four cylinders instead of eight) and mechanics report that the plug wires and plugs are bad and need to be replaced. This has happened three times so this leads me to believe that the plug and wires are not the problem. Computer says that the code indicated the plug wires and plugs but a lot of money and time seems to disprove the diagnostics. Seems like the truck is firing way to hot or something and burning up the plug wires! Any ideas?

Have not been able to get the exact codes but mechanic says that the codes point to the plug wires or plugs but something is messing up the plug wires each time they are changed.

After putting on new plug wires this weekend the service engine light was turned off and the truck ran great for a day and half then the service engine light came back on. Took it back to the shop and the machine said that the truck had a bad catalytic converter on bank one. Does this make sense? The truck ran good for a few miles then it starts missing and this is becasue of the catalytic converter? Could this cause the plug wires the have trouble on the three sets that I pt on it in the past few months? HELP PLEASE!

My dad has a 1997 fi50 with the 4.6l vin code w.
August of 08 the check engine light came on code was p0402 egr exessive flow so we put on new egr, egr solinoid, and Dpfe sensor light stayed out until about a week ago light came on checked same code p0402 thought dpfe was bad took back to autozone got new one (has 2 year warrantty) put on cleared code, stayed off about 15 mins. Came on checked code now it says p0401 egr insufficient flow cant figure it out any help would be great. Thank you.

Its a brand new sensor could it be bad already.
