check engine light from hell
i guess you can tell my mood by the title of this post...
1993 F-150 5.0L 218,000 miles
check engine light is on. Code is saying EGR valve. I replaced the EGR valve ($160.00), and also the EGR Position Sensor ($32.00)
i replaced both O2 sensors about year ago as well as BOTH catalytic converters.
and that light is STILL on...
can anyone give me some advice before I reach up in there and unplug it?
the only clue to a possible problem is a strong unburned gas smell when it starts up. other than that, is runs great.

<i>No clue what the code was. I took the truck to a shop and was told the code indicated the EGR valve. They didn't replace the parts, I did. </i>
Not that easy, the error codes are not that "cut and dried", the computer indicates the problem is in the EGR system but doesn't say exactly what the problem is as you are probably now aware.
Could be the valve, could be the control, could be the vac line to the control or valve and it could be the sensor that reports the valves position to the computer or a combination of any of the above. Only testing will show the true cause of the problem.
If the shop lead you to believe otherwise they were mistaken.

The old OBDI system only requires the neg cable removed to clear the code. OBDII which is roughly late 95 and on just requires a scanner. Either pick up a code scanner from the autoparts store and learn to use it, or visit fordfuelinjection.com and learn the 'paper-clip' method of pulling your codes from OBDI.
