    When I turn the key to start the car there is a hesitation before it starts.
    I thought it might be the battery but the battery light has not come on. Then I thought maybe it could be a starter problem. I'm sort of dumb when it comes to cars.

      Are you saying there is a starter motor hesitation before it cranks? If so, nothing wrong with your thought process. I'd have to make sure the battery has a full charge, all battery and starter motor connections all clean and tight. Good voltage and ground, not much if any voltage drops across wiring circuits.

      I also thought about your ignition switch and if you have automatic, some type of neutral switch issue? You need to do some testing before replacing parts. Any testing at the starter, make sure tranny is in park or neutral and the parking brake is set.

      Some of the national brand auto stores will test the starter for you, if you take it off and take it to them.

    When I make a left turn I hear what sounds like sloshing water and water comes into passenger compartment. I don't on r
    This first occurred during or just after heavy rains. However - Rain has stopped, water is no longer coming into the passenger compartment, but I still hear the sloshing sound on a left turn. I don't hear this sound on a right turn.

      two possibilities i can think of
      1. water still trapped inside dashboard ducting
      2. heater core has developed a leak

      if your heater core has gone bad it will start to leak coolant into passenger compartment. it is located within dashboard area, sometimes directly in the middle, but usually more on the passenger side. when it leaks, it will drip coolant into cabin area, and you will be able to smell it

    Engine sputters/loses power
    When car has been running 20+ minutes, the engine sometimes sputters/loses power and the "check engine" light comes on. I've had two sensors replaced but no luck. Any suggestions for what's wrong/how to repair welcome. Thanks.

    PO441 AND PO455 CODES, NOT THE GAS CAP
    Thank you in advance, I have a 2007 scion tc that just got transported across the country via truck transport, and now after the trip the check engine light came on. The codes read the following, P0455- Evaporative emission control system pressure leak detected- ...

      You need to do a smoke test to find the leak. The most common cause for these two codes is the gas cap but when that does not solve it you may have a leak at the leak detection pump. That is why I say have a smoke test done because I don't want you replacing the LDP (which you could easily do) and get disappointed if it don't solve it.

      By the way, you can build your own smoke machine if you go on YouTube and use search term "DIY smoke machine"

    When changing gears, I can feel my car accelerate, why is this?
    battery light came on 3 times but for less than a minute but battery is not even 2 years old. Also, when I turn on the car, it makes a loud screeching noise but if I turn off the car and then turn it on again, it stops. the noise also starts when I turn on heater ...

    Why does my car die when I turn on the ac??
    2006 scion tc and the car has a new throttle body because the Toyota dealer said it would fix the random stalling that was going on while driving but they were not a 100% that it would fix the stalling when the ac was turned on.

      Did they also replace the IAC(idle air control)valve that is normally bolted to the throttle body??If not I would replace it.Anytime the ac is turned on it creates a additional load on the engine,so this valve allows more air to bypass the throttle body so that the cars idle will raise,compensating for the drag the ac puts on the engine.

    Why does my `06 Scion tc die when A/C is turned on?
    The car is a 2006 scion tc with a 2.4L AT trans. I had Toyota work on the car and told me that the throttle body was bad so I put one on and the car still dies when the ac is turned on even if I rev it up and turn it on.

      Hi tjlollino, The a/c/ puts an extra load on the engine so the computer is suppose to raise the idle when the a/c/ is turned on,which the I.a.c. motor is suppose to do. It could be that the idle air motor needs cleaning or it is bad .Don't pull the pintle out of the i.a.c. motor unless you are planning to replace it. There are specs. for checking the resistance and voltage in the sensors and proceedures to follow to avoid damaging the processor, so I suggest purchasing a repair manual for your model if you intend to attempt it .

    When changing a 2008 Scion XD Camshaft Timing Oil Control Valve Sensor, do I need to reprogram the computer?
    I changed the sensor and the car starts but doesn't stay on, it only stays on if I hit the gas.

      First question - which sensor was changed? Was this the camshaft position sensor? Second question, which installation steps were followed for the cam position (CPS) sensor? Here are the removal and install steps;

      Remove the wiring and retaining screws of the sensor, then slide it out of its mounting hole. Examine the sensor for damage from impact, as this may indicate movement in the camshaft or sludge buildup that will need to be addressed before replacement. To replace, simply insert the new sensor in the mounting hole, and replace the retaining screws and wiring.

      A defective camshaft position sensor will set a trouble code that must be cleared. Clear codes with a code reader, and then drive the vehicle through two drive cycles consisting of driving around town in stop-and-go traffic and then a few miles of highway driving. Turn the engine off for a few minutes between cycles; this should enable the readiness monitors. This drive cycle is known as the "relearn procedure," and each manufacturer has its own specific way to accomplish it. Usually will require around 20-30 minutes of normal drive time.

    When the AC is on and I turn left my car makes a strange noise (sounds like water and squeals) and leaks (cont'd below)
    on the passenger under the dash water. Now it has stopped blowing any air through the fan. HELP! PLEASE! I just had my oil changed right before this started happening.

      Sounds like the weep hole is clogged on the ac.Ever noticed water dripping or puddling up on the ground under your car when the ac runnin,thats where the water comes from.Look for a hole near the bottom of firewall(pass side)and it normally has some black silicone around hole or itl be a plastic tube.Might have to lay a piece of cardboard down,lay on your back and look near bottom of car to find it.You also might try turnin the ac on for a few minutes so you can tell where it is,cause a lil water might drip out.Take a coat hanger and try to push it up in the hole,goin in and out until you get a good stream coming out.Youll know when you break the clog free

      When the battery cables are removed,the computer has to relearn its idle stradegy.It can sometimes take up to 40-50 restarts and sometimes the car has to be driven for 20-30 miles

    My car started to shake when around 60mph. Car was making a loud whining sound. The car is leaking fluid, won't start.
    125,000 miles. Just had an oil change and tires replaced.

      What kind of fluid is leaking?Is it oil,power steering fluid,tranny fluid,coolant?Power steering pump or water pump bearing couldve seized up.Remove serpentine belt and verify that every pulley spins freely except for crank and cam pulley.Car wont have the power to start if a pulley is seized.Try to start car while the belt is off,then turn back off as soon as you verify start/no start

    what is vapor vent valve and canister?
    How much should these parts and repair cost.
     
    • Jimm
      7/1/2013 Jimm
      The vapor canister and vent valve are components in the emission control system. The canister collects fuel vapors instead of releasing to the atmosphere. The vent (or purge) valve controls the vapors and pressure / air flow through the emissions system.
      Check the many on-line auto parts sources, such as; www.partsgeek.com, www.carpartswarehouse.com, or www.rockauto.com for the replacement parts. For example, they (RockAuto) list the vapor canister from around $217.00 and the vapor vent (purge) valve from around $42.00 for your vehicle.

    What's wrong with my car?
    Over-heating problems. Screeching at start up. Loss of acceleration and more play with the pedals. Eventually lead to a break down with white smoke and a loss of engine oil. The oil drip pan light was lit.

      Smoke from the exhaust and loss of engine oil means that the piston rings needs to be replaced.
    • frankiedonnn

      In other words it's burning the oil.This can cause other symptoms.
    • Jimm

      Several possibilities; faulty / worn cylinder head gasket, leaking radiator hoses, leaking radiator - to cause the loss of fluid and the overheating condition.
      Before spending any money for repairs, have these two (2) tests performed to determine the engine sealing and pumping ability; compression test and cylinder leakdown test. If the piston rings are worn, then you may have low compression readings in all four cylinders - for example. There may be the condition of the engine cylinder head gasket is leaking or ruptured - there may not be anything wrong with the piston rings at all - but you must determine the engine sealing integrity with these two tests.

    My engine won't turn over but it's not the battery. Could it be the computer not telling the spark plugs to turn it over
    It's not out of gas and the battery is not dead. The spark plugs could be the problem but I doubt all four would go out completely at once. It has had no problem like this yet and I just drove it this afternoon.

    When I brake my engine makes a "winding" sound
    Whenever I brake, my car's engine seems to be making a sound like it's winding down. I thought that it might be the brakes, but my 20000 mi. service said that I still have 40% left in my front brakes. Any suggestions?

      This vehicle is still under warranty and you should take to the dealer.
