Engine light on and shaking

[Bio-Tech]

My wifes truck 2000 F350 Dually 7.3 has a problem. The engine light will come on and the engine will shake really bad and then after a few seconds it will go out and act fine the rest of the day.
I took it to a local mechanic and he said he put it on a scanner and it said #2 and #7 injectors were sticking. He ran some cleaner through it on a machine and that didn't work. He said to drive it for a few days and see if it clears up.
It seems like it only does it when the engine is cold....after a you drive it a while and the engine warms up the engine light doesnt come on again and it runs fine.
I had Advance Auto check it on their scanner and they said the engine light has to be on for them to scan for codes.
Any help would be appreciated!!

Oh and does anyone know where I can find the lay-out of the firing order of the fuel injectors? He said it was #2 and #7 and he said they were both on the driver's side. We had one changed a few years ago and they said it was the one on the drivers side closes to the fire wall. They said that fuel injector told all the other ones what to do???
Thanks!!!

My money is on UVCH.... (Under Valve Cover Harness)

Do you know what the actual code(s) was that he got?

#2 and #7 are on OPPOSITE sides. Cylinder 1 is the front right (when in driver seat) and 2 is front left. They alternate back and forth, so all the odds, 1, 3, 5, 7, are on the passenger side and evens, 2, 4, 6, 8, are on the drivers side.

And NO, one injector does not tell the other ones what to do.

So this mechanic does not know what he is talking about!!!! #2 and #7 are on seperate sides which means pulling both valve covers!!
Maybe it's not the fuel injectors at all?!?!?!?

The guy at Advanced said that all the injector's are the same except #8 @%$#$@$
Now I don't know what the heck is right or wrong?

Their is NO V8 engine where 2 and 7 are on the same side. That tech

Edit: Holy caw an advanced auto tech that actually know something Yes the #8 injector is different. It is made to reduce injector noise sine #6 and #8 are right after each other in the firing order.

Thanks for the video and the info!!! Now I just need to find a good diesel tech in my area!! That shouldn't be too hard (ya right) only been looking for the last 8 years!!
And NO ToMan07 I do not know what code he got out of the truck! Sounds like he is fishing to me!!

Ok, so from what I have learned here and watching videos on the web. If I have a mechanic do a "Buzz Test" then will that tell me which injector is sticking if in deed that is the problem?
