Misfire, Random ping, and black smoke
I made an earlier thread about my engine regarding the firing order. I sorted that out, and replaced the original factory coil pack that was sitting behind the power steering pump, along with all of the plug wires.
The truck runs better than it did, but it's still misfiring and now is black smoking out of the tailpipe. I can hear what sounds like a ping coming from one of the cylinders. I tried disconnecting the MAF sensor, but it didn't change the running condition much.
Any idea where I should begin looking next?
