Please don't turn it back on. Unplug your computer from the wall and examine the wall socket for blackened or burned sections. It is likely that dust has caused a short in your computer. Sadly, most times this means that you are going to need a new computer or at the very least, some new parts. Take it to a reputable computer repair shop near you and have them test the power supply and other components to see what is salvageable of your computer. With any luck, your hard drive contents MAY have survived but there is no guarantee.

The smoke could be caused by blowby around the piston rings. Pour a small amount of transmission fluid in the spark plug hole and turn the engine over several times. Check the plug for fouling. Also check the coil wire for spark.
Unplug the unit and do not plug it back, I can almost picture someone doing this, watching the sparks and smoke and oh the lights dim--Be smart here===either replace it out of hand or take to a repair shop to see if worth fixing or not and do not attempt to turn it on again.
HI, Spark plugs or wires will cause engine shaking, but not SMOKING. I would identify the source of the SMOKE first. If it is a fuel leak the smoke may turn to fire. This is not meant to scare you yet with out seeing it I know a fuel leak will cause a engine to "shake" and create smoke as the fuel touches a hot exhaust manifold.
You changed 6 coils, but you didn't change spark plugs? The new coils give strong spark to burn off resisdues from your old plugs plus what ever left inside the combustion due to bad old coils causing smoke and bad ordor. Change all new spark plugs so you can have good ignition to burn off all junks inside combustion chambers. Smokes are at the beginning, but it will go away after less than 10 minutes.
If it is not going away you may have other problemS:
Rich mixture causing engine check light come on.
Check if engine oil level.
Check if your coolant level.
Open the oil cap to see if you have milky stuff. If there is milky stuff then you have bad head gasket.
Let me know what is coming out so others can learn from your experience. Good luck.
Your truck is fuel injected . Black smoke indicates a rich fuel mixture. This could be caused by numerous items. A faulty sensor, a faulty injector, a misfiring spark plug are some of them. To really zone in on the problem, a computer diagnosis is required to note sensor readings, and repair as necessary.
It can be a bad distributor or bad distributor cap, the while smoke can be because of no-spark the engine becomes flooded and as the gas burns off the exhaust is rich thus the smoke (maybe a grayish white in color) and the 02 sensors may be turning on the check engine light. When the vehicle is not starting the next time it shuts off check for spark and get back to me. Good Luck
No it has not been overheating or losing coolant at all it just has been running rough and poorly (loud) it was not smoking till he took out the old spark plug and put in the new one he said it was smoking out all that had been backed up into the cylinder due to non working spark plugs (there was oil on the spark plug)
