1994 Chevrolet C3500 7.4L Misfire
Posted to GM Driveability on 10/1/2005 23 Replies

This Chevy Truck fries the number 1 spark plug wire right off within one day! I realize that the cylinder is getting too hot, but does anyone have any ideas why? The ign. timing is good, no vac. leaks, and I put in a cooler thermostat. ( 180 deg.) Thanks in ad...
