Hi guys
Just fitted an g13ba engine to my 1997 sierra, shes running rough as guts, only thing not connected is the alternator due to different wiring, could this cause it to be running rough? Only other thing could be vacuum hoses as they were all over the shop. Any help would be great.
Cheers

Without a working alternator, your battery will be drained in fairly short order,

As the level of electrickery drops, the coils/plugs will give a weaker spark - and the engine will run like a bag of $hit before stopping altogether.
