I am throwing a P0172 code (Running too Rich - Bank One) I have already replaced the front O2 sensor. Anybody have any Idea what it could be. My car is hesitating and has no power at all. 1996 Honda Accord LX. Any Help would be great.

 

does your car hold fuel pressure when turned off? if not you may have a leaky injector

 

I'm Not sure. How do I check it?

 

pull the vacum line at the fuel pressure regulator and see if there israw gas in it.
Any main't ever been done? spark plugs? air filter?
Any other codes stored in the ECU?

 

I did a tune up about 6mos ago. Plugs, wires, fuel filter, air filter, cap and rotor, egr valve.
