Hello new to this forum. I have a 1994 Chevy k1500 it started running bad a few weeks ago. changed cap, router plugs and wires also have changed the MAP sensor TPS, IAC EGR solenoid and EGR. shes still bucking and sputtering mainly at about 30-35 MPH or if im holding a steady pressure on the throttle the RPM's dip as well and come back up at these speeds also stalling if sitting still to long or even sometimes while im braking to a stop. have heard that if the tourqe converter is sticking it can cause this as well any suggestions.

OH yeah have already tested the ignition coil pulled coil wire and got about 2 1/2 inches away before truck died good fast and strong spark. Mods done is headers and 3in dual exhaust been done for a while so not the issue.
