Recently my daughter's '96 Honda Odyssey (w/150,000 miles) Check Engine Light came on and the Code reads PO 171. The code stands for System Lean /Bank 1.
I bought the car brand new and it has been running fine ever since. The only minor complaint is it takes some long cranking on the starter when first starting the car in the morning. It may take 5 seconds before it starts and this happens intermittently. I mention it only because it may have something to do with the Check Engine Light.
I will be changing the spark plugs since I am overdue on that task anyway. Has anyone else had this Code and success in fixing the problem???
