NooB problem... i hope
i just bought this truck
1993 f150 flare side 351w, auto, with push button t-case. i believe the trans is a e4od. Its got ~180k on it but runs like a champ
the problem is i keep getting a check engine light but only when im driving. i can run the engine in park for an hour and the light wont come on. i tried to scan the ecu put since i turned off the truck to borrow a scanner from O'reilly i had to turn the truck off. when i started it again, the CEL was off and no codes stored in the computer!
it takes a minuet or two for the CEL to turn on when im driving it.
what is going on? my thinking is transmission related, but it doesn't seem to be shifting wrong
i did recently do a tune up, though i dont see that as being the problem...
spark plugs, wires, cap, rotter, oil & filter, air filter,
i read some where that it might be the EGR valve is not getting enough vacuum?
anyone know where i can get a cheap obd1 ford scanner?

Ford Fuel Injection » How To Run a Self-Test here is a link on how to get codes without a code reader.
However you should be able to get an Equus 3145 for around $30.00 which makes life a little easier.

As Lazy K said, the Equus are about $30-$35 each. I bought mine from O'Reilly.

They make an extension cord, of sorts, to use with those scanners. It allows you to put the scanner in the cab with you. I bet Auto zone or no one else has one locally for you to get.

BRILLIANT!
I just didn't know if the scanner would prob something in the computer while driving that would cause an issue on the road. im used to either carb'ed or OBD2 stuff
i'll make up a harness tonight if i can find enough connectors
i'll post what the codes are if/when i get any
thanks

Your scanner will only pull live data if it's equipped to do so. If you bought the Equus brand then it's not set up for it.
But like I said, if you got a CEL and then didn't find anything stored, there's a deeper issue at work. But I suppose we should see if you get anything with the reader or not first.

well apparently it wasn't just during drive. but when i was maintaining about 2000 rpm like i would in drive. i tried running the engine at that RPM in neutral and the CEL came back.
anyway these are the codes i was able to pull and what my book says they mean
311 - thermactor air system problem- no operation during engine run self test
332 - insufficient EGR flow detected
538 - insufficient RPM change during Dynamic Response Test - this may have been my fault for not going WOT soon enough - i was reading at the same time so im not too worried about this one yet
311... so since im going to delete the smog pump any way, i dont suppose i should worry about this as much
332... I'm planing on the EGR delete anyway so... not to worried about it either
I passed emissions in-spite of these problems
still any other input would be appreciated.
im planing on the MAF conversion when i get the money for the stand alone trans controller im thinking B&M

You'll probably want to get ahold of Conanski if you're planning on the emissions delete. There's ways to eliminate the system without future codes being triggered.
As for the 538- I usually get this code too and I suspect it's because I don't hold the pedal to the floor long enough. Not that you need to hold it for longer than a second, but I think doing more than a quick slam to the floor is needed.

update on my problem,
the shifting problem wound up being, a bad throttle position sensor.
after changing out the IAC, tearing off the egr and air pump, and replacing the cat with a new style cat.
so now im running good with a new throttle position sensor. my check engine light still comes on but its due to the egr not being there, the plug from fordfuelinjection for the egr plug did not work for stopping the check engine light.
but problem fixed
