What does it mean my rpms won't go past 2k at idle & black smoke starts coming from the ehaust?

I don't have RB, but the way you're describing the problem, it sounds like your ECU is in limp mode. This is most likely caused by a bad Air Flow Sensor. Have you tried a known working MAF?

totally limp mode . the black smoke means that your motor is dumping lots of fuel in the cylinders to run it really rich.

check your maf and the plug for the maf. if thats all good then it might be wiring ( could be bad ground ) then if you have nothing after that. grab some codes from the ECU and search them up on google.

I havnt tried a working MAF sensor yet. I dont know anyone who has a working one.
And yes it makes sense cause he smoke smelled like burning fuel.
