Hi, I have a 1995 gmc 350 with 277000 miles on it. Today I cleaned my throttle body with some TB cleaner, drove about 5 miles and it died,started, drove about 100 feet and died again. I was trying to start it, left the ignition on and the coil started somking. I replaced the coil and it fried instantly within a few rotations. Does anyone have any idea where to start with this? Thanks for any help.
