the LB7 has injector issues but gm extended the warrenty to 7yrs 200k but just on certain circumstances with the injectors. the LLY does have cooling issues its a head gasket problem but is only on 05 and 06. and the wiring problem on the LLy is for #2 and #7 injector plugs factory used straight plugs and pulled them to plug in but from them having tension all the time its loosens the terminals and breaks contact when this happens you loose 4 cyl. gm revised the plug to a 90* plug and a bracket to hold the wire from pulling its a whole update kit
