Why does my 2014 ford ranger emit excessive black sooty exhaust smoke when under load / accelerating?

While driving the vehicle with this condition (possible oxygen senor issue) will it cause any further problems before the initial problem is fixed?

Sounds like either an Oxygen sensor has failed or is failing or you have 1 or more injectors leaking. If your vehicle has a check engine light on then check that first. If not you're going to have to do some digging around and testing to see what has failed or is failing. There are many ways to test them. If you're going to do the work yourself I would suggest going on YouTube and watching videos on how to test the Oxygen sensors or the injectors.

    Will driving the vehicle whist experiencing this condition cause any further complications prior to the original problem being fixed?

    Yes, when the injectors are leaking (if that is your problem) it can over time cause a build up in your catalytic converters and clog them which in return could cause a no start. also running with leaking injectors causes excessive fuel consumption and rough running conditions.

Have LT 1536 . Smoke started coming out the exhaust but engine sounds healthy

Depends on the colour of the smoke.
Unlikely an engine will sound healthy emitting black smoke - excess fuel.

An engine could sound healthy emitting white smoke (steam from coolant) but not from white smoke (excess unburned diesel).

Most engines emitting blue or blue-grey smoke from burning engine oil can sound very healthy.

Would a faulty egr valve on my 02 PT Cruiser 2.2crd cause excessive black smoke and injector knock under full throttle....thanks

black smoke is over fueling and although the turbo appears to spin ok the vale variation actuator may not be operating correctly
there are vanes in the exhaust turbine housing that are altered to increase the exhaust gas flow onto the turbine blades for quicker acceleration and these vanes are operated by a vacuum actuator and rod by a sensor
the vanes are subject to extreme heat and can rust stuck open or the hose gets hard and cracks
s not allowing the vanes to work
I would be concentrating in this area before the EGR valve
run the fault codes as well to get a better idea of the possible fault as some systems only put the light on for extreme conditions in engine and transmission

Have excessive blue or white smoke from exhaust when truck is started after sitting for a few hours 2005 f250 6.0 ehgine

is it a diesel or gas engine?
Usually excessive blue smoke on start up indicates oil is getting into the combustion chamber. It could be piston rings or valve seals.
Quick check, drive it within operating range and speed. Either use the rear view mirror or get someone to drive it and you follow in another vehicle. Accelerate, then take your foot of the accelerator. Blue smoke under acceleration indicates piston rings / pistons. Blue smoke on deceleration or the "over-run" indicates worn valve guides / seals.

White smoke can indicate coolant in the combustion chambers / leaking cyl head gskt, or incorrect fueling. If brake fluid gets into the combustion chamber it will generate a lot of white smoke from the exhaust. However, that would entail a leaking brake master cyl and a leaking brake booster.

Good luck.

How much should my Ford ranger 2.5td be smoking,is it normal for diesel engens to smoke.

Sometimes diesel engines will put out black smoke under extreme acceleration. Other than that, they shouldn't smoke. Black is excess fuel, White smoke is water and bluish is oil. White smoke on a cool morning is not necessarily a sign of a problem unless it happens every time you start it through a warm day. Hope this helps.
