You guys are awesome. I got exactly 2 replies on the ford truck NG.
30+ here. Oh well.

Found the fuel filter and changed it. Didn't help. It was old anyhow
so no problem. To quote a famous (RCM) American, shrug

Followed the instructions on the autozone link that Glenn posted. Got
3 codes that, according to the card Rick scanned (Thanks Rick!!) tell
me the following (in order):

53 Throttle position sensor above max voltage
63 Throttle position sensor below min voltage
31 EGR valve position sensor or EGR vacuum regulator below min
voltage

Those results agree with the autozone page, so you got the right
setup, Rick.

Just a bout the time I got that much info, it got real dark and
started raining on me. yuck. So I came in to look up the codes.
If it lets up, I may just go back out with the Big Lights and follow
those up. Likely will check out that idle air valve, too, as it looks
fairly easy to get at. The autozone page gives some quickie
voltmeter/ohmmeter type tests for those devices, so I can try to see
if I can verify any of these. Looks like I may end up doing as Larry
did and hitting the boneyard tomorrow.

Like I said, you guys are awesome. I'll let you know what I find out.

Appreciate all of the help!

Good luck with it! You can get the OBD-I tester at Wal-Mart for about $25.
If you don't mind, please stop bragging about getting two responses in a
Ford truck forum. :-) For those who don't know, the Ford truck forums are
a great place to brag about what kind of motor and exhaust system one has,
but not so good if you really need help. He was lucky to get more than one
response, unfortuantely.
