Fuel problem try changing fuel filter and blow inlet pipe backwards with an airline first before you start plugging things in,remove fuel filler cap before you blow though in case you explode the tank,start here first if this doesnt work then call you local mobile mechanic to check further

the p0325 code pertains to a knock censor. the p0340 is for your cam shaft sensor. i've had this problem before. try replacing the cam shaft censor first and run the codes again to see if the other still comes up. it should fix the problem. hope this helps
HI . make sure the two sensors are replace from the dealer along with the harness going to the top of your intake and make sure they silicone the plastic grouments that cover the sensor holes to keep water .
sounds like the electrical system is being grounded out track all recently added accessories, amps radios etc. dosent really bsound good about the noise in the morning, but still sounds like electric short.
That's actually pretty normal. It's just the engine warming up. Even my friend with a late model Acura has the same prolem so she warms it up before driving. I've heard experts say that warming up your car is just a waste of gas so I presume that the initial knocks are not to be worried about. Something to email Click and Clack on NPR about but I really don't think it's an issue. When I've had two cars run into the 200,000 mile range it didn't seem to be an issue. I always changed the oil before or at about 4k miles.
Take the car out for a long drive and enjoy it. And don't worry.
