Engine light
I went into the dealer today and got an oil change, replaced fuel filters and air filter. This evening while getting on the highway, the engine symbol illuminated on the dash...is it possible any of those services caused this?
Is it safe to continue driving?

Alright, just got back from getting the codes read at Autozone, all of them had to do with injectors having "low circuit".
PO282, PO279, PO273, PO267, PO264, PO261
Which are Cylinders 8, 7, 5, 3, 2, and 1 have "injector circuit low".
The slip mentions possible causes as:
--Open Circuit condition
--Coil to coil short
--FICM poor connection fault
--faulty fuel injector
In addition to the information above, I should not that I added the REV-x oil supplement immediately after the oil change to try to somewhat tackle my sticky injector problem. It has worked well, started up today smooth, which is the first time its done that since I have bought it a few months ago. Anywho, the truck is running like a dream now, funny its putting out codes, lol.
Any thoughts?

The codes are from a previous problem. Delete those old codes and re-run the vehicle for a few days to see if they come back......
Also, check the voltage on your FICM according to the voltages in the Tech Folder..... http://www.ford-trucks.com/forums/89...procedure.html

All those low circuit codes definitely indicate a FICM problem. Did you have Autozone clear the codes?

I did not have AutoZone clear the codes, I will go back up there tomorrow and have that done. Is it possible the dealer caused the FICM code or maybe just pure coincidence?

Just an update, this morning I had a VERY hard time starting the truck (cold start). After trying for a little while and a bunch of black smoke later it finally sputtered to life, and ran very rough. I hit the high idle and after 15 - 20 seconds it finally smoothed itself out, and started running fine. Still running great and starting great while warm, does that sound like FICM still? The check Engine light is still illuminated also, Autozone said they are not allowed to "clear" codes here...

Agree 100%
your FICM has low voltage
you maybe able to fix it if you can solder per tech folder
I would also fix it soon its KILLING the injectors Every Cold Start
maybe even plug it in
IIRC you can unhook Batts for 20 min with the headlight on to clear codes or maybe that just resets some things not shure
That Rev-X has Masked the root cause

Well another update, the truck no longer will start at all cold. So I just got it towed to the Ford dealer, waiting to hear back from them, even though I feel as though I know what they are going to tell me, lol
