Lay off the wacky-tobaccy for a while honey and you'll be able to think and type coherently once again.

I work at a NAPA Auto Parts store, we aren't just a bunch of "idiots" who graduated from high school and read some books, we know our stuff very well, and some of us are ASE Certified in diagnostics and troubleshooting. However, AutoZone, PepBoys, CSK, etc, don't know a lot from what I have experienced, one AutoZone in my town tried to tell me that my 7.3 Powerstroke Diesel was running rough because it needed new plugs and wires.. 0.o. In a case like this, take it to an ASE certified mechanic or shop, computers can only tell you so much, like some people have said do a compression/leakdown test and find out where the problem lies.

Auto Zone, Sears, Pep Boys?
Those people are morons that only know how to read a computer code and look in a book for what to REPLACE.
The reason they work there, is they don't have the knowlege, experience, or basic troubleshooting skills needed to make it in a real shop.
Most of them just graduated highschool, went to this stupid class on how to remove a wheel, or battery from a car.
If they don't have a computer to tell them anything, they can't figure it out.
I disconnected a spark plug wire and went to Auto Zone to see if they could find the problem. (no codes)
They wanted to replace my fuel pump. (which by the way was fine)
The only thing those chain stores are good for is buying parts.
Never trust anything they say when it comes to troubleshooting ANYTHING!!

well the mechanic your co worker referred you to did what me and most mechanic would do. Read the code and go from there. I would have cleared the code and if I got the same number 6 cylinder again I would have done the same (plugs)
Changing the injectors I would have not done (there not cheap). I would do the compression test and that will tell you a whole lot more.
It's a hard thing to troubleshoot.

Milky oil with a strong smell of gasoline will indicate a damaged piston.
Intake valve would cause popping when accelerating.
Exhaust valve exhaust pipe would be snow white.
Have someone recheck your spark plugs & wires. Use an inductive timing light & check each wire individually.
