Feels like a misfire

Truck is bucking and missing every 10 seconds or so and will stall when taking off in drive sometimes but fires right back up? I got a lot of codes in the torque pro app but some are in grey. Not sure what that means. EGR has been deleted so that's why I got those codes. I was cleaning the back of the truck the other day and found a can of quick start

. Guess that might be why i got codes for glow plugs also. I'm gonna post up pic of my codes and numbers of truck running at idle in drive. If someone can point out something... so far I see I got a code for cylinder 6 contribution? It's in grey tho whatever that means.

I didn't a buzz test and it clicks good, sounds almost identical to the other injectors and it reads 1.3 ohms or so like all the other ones also?? What also to check ?

I maybe hearing wrong but it sounds like #6 has a bit of a pitter patter instead of steady ticks like #4.

That only checks the electrical solenoid that moves the spool valve controling the driving oil. It does not check the fuel plunger, nozzle tip, or sealing ability of the injector gaskets. A contribution test done with an IDS will.

Answer to 3:03 post. Tone matters.

Never mind, it sounds alright I think. Not sure why I'm getting that grey code

I don't have IDS, just torque pro. Guess the only way to know for sure is to swap out injector with another one of the other cylinders and see if that problem goes to that cylinder.
