Question
engine check light is on. p0350 is the trouble code. changed plugs, 4 coils, and still have the same code showing up. vehicle stuttering, black smoking, lossing power andt stalling

Answer
Hi Andre -

That code is "Coil primary or secondary circuit malfunction"

Could not necessarily mean the coil(s) are defective. Have you checked the wiring?harness to the coils? If there is a loose or corroded connection, that would cause your issues.

When you reset the code does it come back right away, or takes a while?
