ok not sure what this is related to but im guessing its fuel pressure or maybe bad fuel... when at idle o2 volts go from .300 to 700 when i drive around slow its fine but when i start to give it gas the o2 volts will drop to like 100 if i hold it they will start to go up to 400-600 if i get on it a lil hard the retard degrees will go to like 15, i let off imediately and they will go to 0, one time when i gradually slowed down it went from 15 to 2 and then to 0 was at 2 for a short bit but i wasnt completely off the gas. is this a fuel pressure problem, fuel quality problem or any ideas???

thanks
Lance
