Hmmm.... My buddy has a 96 jimmy that did that to him. All it was was the cat was full and needed to be replaced. Now he had the kind of cat that doesnt have a drain. I dont know about ours though. But thats all i can think of bro

Injector, maybe.

If it has 8 plugs, and you get a "no spark" on #3, you need to determine which plug isn't firing - intake plug or exhaust plug. That way you know which coil is bad. I've seen bad ignition modules cause a coil to malfunction, but with an ignition problem on the dual plug engines you normally get stored ignition codes. Could still be a dirty injector.
