    Engine hesitates when accelerating beyond 2000 rpm. if kept below that will run perfectly fine.
    when it's in park i can go well above 2000rpm without any rattle or shaking. only happens when in drive and when accelerate quickly . feels like stalls.

      First question - when was the last fuel filter change? How many miles since the fuel filter was replaced? If more than 2 years / 24k miles - do this as the first step. The typical unit price around $9.00 to $13.00 - from any of these aftermarket parts sources;,,,, - to list only a few possibilities.

      Along with this step to change the fuel filter - check the OBD (on board diagnostics) system for any stored fault codes - there may be a stored fault code even without the Check Engine Light displayed. The OBD system can be tested for free - at any lcoal auto parts store in your area.

      Please post a reply with any specific stored fault code number for further assistance.

    Why do I only get hot air from my heater system, even though my a/c works?
    mileage 178,000. My ventilation system only blows hot air. My air conditioner still seems to work. It is a constant. When I first turn on my fan, it clicks for about 30 seconds. No warning lights. No check engine lights. No other problems.

      If your saying no cold air with temp control on cold, check to see if compressor is activated. Another issue could a problem with temp door, under the dash.

      If you have a fan problem, I'd have to check the wiring circuit for the fan, voltage and ground.

      Thank You. I now believe it is the temperature blend door actuator.

      Most likely you have a bad blend door actuator that is stuck at the warm setting, and you mentioned hearing clicking which is often a symptom of the bad actuator.

      Thank You. From all I can determine, the Blend Door Actuator sounds like the problem.

    Help with engine sputter which acts like rev limiter, following timing belt replacement?
    Wife blew timing belt at 55mph. Garage replaced water pump and timing belt for $927. Now engine sputters between 3200 and 3500 rpms which reminds me of a rev limiter. Check engine light on. Code says cam position sensor. Replaced cam position sensor for $43 and no ...

      That is very possible or perhaps you bent some valves when the timing belt went. either way
      I would definatley take it back to the repair shop that did the work. There should'nt be any
      charge for this work.

    (Why doesn't my car idle?) My car does not idle. i have to press the gas for it to start, and as soon as i let off itdie
    120,000 Miles The car will not idle when its cold nor hot. It sat for a few months and i just fixed a head gas. Put it back together and now will not idle. ABS brake light is on. Check Engine light IS on.

      Sounds like Vacuum leak or no vacuum detected maybe from hose off or missing etc. The fact that you have ABS + Engine Idle issue, I'd double check all hoses to make sure they are all in correct locations and not cracked etc. Master Cylinder for Brakes uses vacuum and this might cause the ABS light.

    Why does the car have a bubbling sound when I turn the engine off?

      I'd pop the hood and try to determine the location of the noise. I have seen a blown head gasket before that caused the radiator overflow tank to bubble even after engine is shut off due to exhaust gas that was able to escape the cylinder into the water jacket, but yet no loss of water out exhaust, and no oil/water mix etc. New head gasket and problem was solved. This was a 1986 Pontiac Sunbird 1.8Liter sohc. Same bubbling noise when shut off as the gas pressure in coolant system was venting out the radiator overflow tank, just bubbling like as if a fish tank pump was pumping air into it.

      Rotate the engine with a ratchet and look at those valves in 3 and see if they are moving and see if they close or not and if they do not close, remove the valve cover and check for broken valve springs.

    Why does the check engine light come on when I use regular unleaded fuel?
    The check engine light goes off when I use Chevron supreme unleaded fuel. The owners manual says I should be able to use regular unleaded. I bought the car one year ago. Current mileage is 102,000.

      It is important to use fuel of the proper octane rating in your car. Octane rating is based on the quantity of anti-knock compounds added to the fuel and it determines the speed at which the gas will burn. The lower the octane rating, the faster it burns. The higher the octane, the slower the fuel will burn and a greater percentage of compounds in the fuel prevent spark ping (knock), detonation and preignition (dieseling).

      As the temperature of the engine increases, the air/fuel mixture exhibits a tendency to ignite before the spark plug is fired. If fuel of an octane rating too low for the engine is used, this will allow combustion to occur before the piston has completed its compression stroke, thereby creating a very high pressure very rapidly.

      Fuel of the proper octane rating, for the compression ratio and ignition timing of your car, will slow the combustion process sufficiently to allow the spark plug enough time to ignite the mixture completely and smoothly. Many non-catalyst models are designed to run on regular fuel. The use of some super-premium fuel is no substitution for a properly tuned and maintained engine. Chances are that if your engine exhibits any signs of spark ping, detonation or pre-ignition when using regular fuel, the ignition timing should be checked against specifications or the cylinder head should be removed for decarbonizing.

      Vehicles equipped with catalytic converters must use UNLEADED GASOLINE ONLY. Use of leaded fuel shortens the life of spark plugs, exhaust systems and EGR valves and can damage the catalytic converter. Most converter equipped models are designed to operate using unleaded gasoline with a minimum rating of 87 octane. Use of unleaded gas with octane ratings lower than 87 can cause persistent spark knock which could lead to engine damage.

      Light spark knock may be noticed when accelerating or driving up hills. The slight knocking may be considered normal (with 87 octane fuel) because the maximum fuel economy is obtained under condition of occasional light spark knock. Gasoline with an octane rating higher than 87 may be used, but it is not necessary (in most cases) for proper operation.

      If spark knock is constant, when using 87 octane fuel, at cruising speeds on level ground, ignition timing adjustment may be required.

      Your engine's fuel requirement can change with time, mainly due to carbon buildup, which changes the compression ratio. If your engine pings, knocks or runs on, switch to a higher grade of fuel. Sometimes just changing brands will cure the problem.

      If you plan to drive your car outside the United States or Canada, there is a possibility that fuels will be too low in anti-knock quality and could produce engine damage. It is wise to consult with local authorities upon arrival in a foreign country to determine the best fuels available.

    Why am I losing oil?
    no leaks, no smoke, no oil in radiator. just loses a quart every 300 miles.
    • CVO
      4/23/2014 CVO
      Losing oil works their way through the worn valve stem seals and penetrates into the combustion chamber. No smoke, no leaks.
      See this url
      for the valve stem seal.

      No answer here. If no external leak is really confirmed then it is burning the oil. There is no other cause. One or the other.

      What would cause it to burn oil with absolutely no exhaust smoke.
    • HouseCallAuto
      4/22/2014 HouseCallAuto
      Experiment...Try using full synthetic and see if any change. Also pay attention to how much oil is put in after an oil change with filter. 5.0 quarts exactly. And of course 5W20 oil. Oil can burn gradually and leave no smoke trail, this is not some new anamoly. Your catalytic converters will take the toll.

      You should definitely get a second opinion, it's a bunch of BS. There are a lot of different components that are responsible for reducing the amount of unburnt fuel(hydrocarbon). Certainly it is not your engine.
      4/15/2014 Lisa H.
      Thank you so much for your input. I feel like I'm at the mercy of these smog testers...ugh! If you think of anything else, please don't hesitate to comment. :)

      And after you get it solved WITHOUT a new engine, go get your diagnostic fee money returned from those idiots.
      4/15/2014 Lisa H.
      I appreciate you taking the time to comment. Plus, now I will feel a bit more confident knowing it might not be the engine. Just wish I HAD the nerve to ask for a refund;)

      Pep Boys probably will refund you provided you can back up your story after the fiix. I buy parts from them every day.
