4.2 engines never had a throttle cable, they've always been throttle by wire.
I just replaced one of these engines in a 05 envoy with 46000 miles for a worn thrust bearing surface on the crank. I can get the core for free and was thinking about using it in my 36. would anybody know what I need to use for just an ignition system? the fuel injection is way to ugly for my application, so I'll be using side-draft carbs.
