    well i wanna bring the ranch truck to here so i can have something to drive while i fix the blazer. too much gas in the k5. so my dad replaced the ecm on it and that didn't fix it. so what else could it be? my dad said he would replace the o2 sensor on it since those are cheap. if that doesn't work what else would it be? thanx. later.
