My 2003 GMC Envoy has never stalled, until two days ago. I had a new battery put on and as soon as I pulled out and stoped at a stop light, it stalled. It continues to stall when I put on the heater/cooler fan. Otherwise it runs perfect. I bougth a OBD scan tool and it reads nothing wrong. Please, can you help??
