Lance, Was truck acting up prior to you changing the parts? There are a lot of possible causes for this condition, recheck for vacuum leaks, use a can of starter fluid to spray around intake , carb. base, all vacuum hoses including brake booster if equipped. Check EGR for being plugged/faulty, could be an issue with carb's settings/ float levels/accelerator pump, choke, etc., check for pinched, collapsed fuel line, check fuel pump flow. If all seem OK then try your hunch, check/clean connections and grounds to coil and control module before replacing and try. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
