My minivan runs purfect most of the time, however, if I drive up a long grade, it acts like it is out of gas, runs really ruff then dies. I have used a scanner and get back code ---PO171 system too lean (bank 1). I have replaced the upstream o2 sensor however I still have the same problem. What do I do next? By the way, once it starts acting up like this it usually won't start, or if it does it will run very rough. If it sits overnite it will usually run fine the next morning but will fail again next time I try to go up a long grade, or even if I go for a Highway drive. It has plenty of gas, (half tank or more) and never heats up past normal. HELP! PLEASE.
