Yes I put new plugs in a few weeks ago. Yes I have checked all the wires and they are o.k. and firing to my knowledge. I am in the process of making a boost leak tester, but I checked all my pipe connections this sunday when I put the pump in.

This problem has been around for a bit. It now has gotten worse, and my lifters are ticking non stop. Before the lifter tick would come and go.
When the RPMs get up to 4 k it sputters, the power drops off and I noticed that black smoke comes out the exhaust until I shift, sometimes backfiring.

Thanks everyone
