Sounds like a fuel contamination,purchase two bottles of HEET,in the yellow bottle for gas engines,it is the best for moister and water,and add LUCAS fuel treatment for cleaning the injectors,and fuel system,if possible do not add any gasoline to the fuel tank,it works faster and better with less fuel,then after it has started running correctly add the fuel then.

2005 Chrysler 300 C. Battery went completley dead. Jump it . It holds a charge. Now check engine light on. Runs rough multiple missfires. Replaced battery. Ran good for 10 miles. Check engine on again....


Fill up your gas tank and ad a bottle of Lucas gas treatment/lube to the tank, be sure it's the treatment in a little clear bottle and not injector cleaner. After you've added the gas and treatment drive the car, with the head, driving lights, radio, heater, etc. all turned off. It may take ten miles or more but the check engine should go off and car will run normal. NOTE: Never jump start your car or use it to jump someone else's without referring to your owners Manuel.

have you put into your gas tank any injector cleaner which will clean the injectors so to allow the full amount of gasoline into each piston heads. do this first and drive like 5 miles or so and see if this helps.

I looked up the code and it said p171 was a lean air mixture.
Lucas could help if it were a clogged injector.

Lucas Fuel Treatment
Lucas Fuel Treatment is formulated for both gasoline and diesel engines, carbureted or fuel injected. It gives your fuel system what it really needs - a blend of super slick oils and additives with a high detergent action that allows the engine to operate at maximum efficiency. Also, it cleans and lubricates the carburetor and injectors and causes the fuel to burn more thoroughly for increased power and less fuel consumption. Lucas Fuel Treatment should definitely be used in vehicles that require leaded fuel because it actually replaces the benefits of lead in gasoline without causing harmful emissions. Use it to pass smog tests. Finally, it totally neutralizes the harmful effects of low sulfur diesel fuel.

I do not know what the humming noise would be, exactly. It's kind of hard to diagnose without hearing what and where.

However, I would check all fluid levels to make sure that they're ok, as a start.

WHY IS MY VOLVO USEING SO MUCH FULE ITS A S40 V40


I noticed earlier that you said your check engine light was on, did you ever figure out why?, or is it still on?  How many miles on it, did you get the timing correct after changing the timing belt, what error codes is it throwing and have you done a tune-up recently?

Sounds like you may be passing moisture to the O2 sensor. #1 make you sure you are using a GOOD grade of Gasoline. You may need to add a bottle or 2 or DRI-gas to you gas tank. A good bottle of LUCAS fuel treatment wouldn't hurt at this point either.

Sluggish acceleration


May not be the fuel,but it would not be a bad idea to treat it as such.The NAPA auto parts sells two additives that are really good products,one is lucas fuel treatment for contaminated fuels.The other one is HEET,for water contamination.I would put a full bottle of LUCAS,and two bottles of heet.Put full bottles in for full tank or less.The additives work best with less fuel,so they will work in a consitrated level.If the additives are added soon,they will save the injectors.Bad fuel has been known to damage injectors so much as they have to be replaced.So if I can help,let me know.
