I got this truck and was running rough. Previous owner told me the coil packs are going bad on it. I changed the plugs and put the dielectric grease on the spring where connects to coil pack and to pug. No difference. I have not gotten codes pulled yet. Just getting started in the diagnostics on this.

Try scanning the computer for code/s-You test the coil just the way you test the cylindrical coil's primary and secondary winding resistances
