Re: Got it running -- hesitates when cold
Another bit of info -- today during my running-hot adventure, the hesitation/stumble did NOT go away after warmup. It remained consistently rough at low rpm (smoothed out at around 4K or so). I installed all new injectors from FIC when I pulled the plenum. The car had new fuel pumps installed a couple of years ago by the PO. New GM coils, wires, and plugs.
