    Shaking while on idle and jerking.
    I have a 2002 Toyota Avalon with about 225,000 miles on it. Just recently my car has been jerking around 40 to 50 mph. The car vibrates when on idle, burning smell and im not sure if this is a problem but i see more white smoke coming out of the exhaust.

    When trying to start the car in the morning, the engine turns but will not start until the 2nd or 3rd crank.
    Mileage is 50,000 miles and I have replaced the spark plugs, fuel pump, and PCV valve. This problem usually happens only in the morning and the car will then start normally the rest of the day

    Why is my heater not putting out heat and the temp gauge goes up to the red?
    Coolant level ok. Checked hoses to and from engine after warmup and both cold. First thought is t-stat stuck closed, but only 15K miles on vehicle, and surely it wouldn't ffail already. I drive it offroad in a field with a lot of weeds. Could a stiff dead stalk have ...

      Yes that could have happened but is unlikely...simply take a flashlight under the car and take a close look for any broken wires. Coolant passages could be clogged, same with heater passages. Check coolant level, ensure it is full in the radiator and at the proper level in the overfill bottle. Check radiator cap, if any seals broken it will not hold pressure.

    I cleaned my starter electrical parts & put in a new battery. Car turns over and over and but won't fire up. Thoughts?
    The starter was being fickle and not really working. Seems to be consistent now that I cleaned it up and gave it some whacks. New battery too. But it seems I'm missing some spark somewhere. Alternator?

      First, check the battery and starter cables for their tightness or free of corrosion and physical damaged.

      See this Starting system simplified diagram. Have a help from an assistant to crank the engine, use a 12 volt light tester or a digital voltmeter, apply it to the starter control circuit.
      If there is light or 12 volts and the starter isn't cranking, then the starter is the culprit. Have the starter to bench test for free at the local auto parts stores.
      If there isn't no light or no volts, then the ignition switch is the culprit.
      Check the starter relay and position the Automatic transmission shifter in neutral.

      Note: a 3/4 charge battery is 12.50 volts
      A discharge battery is 11.75 volts.
      A battery under a cranking load and it is reading less than 7 volts,it will be a recycled battery.

      Thanks! Actually got it going and it starts up fine now. Seems like fuel wasn't getting where it needed to be. But now in park or neutral (reverse seems normal) it's idling/revving quite a bit higher than normal. And then there is an occasional lull. Stuck throttle? Thoughts!

      Use the WD-40 to lubricate the throttle shaft and their linkages, it does help.

    Car won't go past 1st gear without a big struggle and once in 2nd gear it won't accelerate
    I've changed out the oxygen sensor and all the spark plugs but still the vehicle struggles when I accelerate. Even in idle if I accelerate it bogs down instead of accelerate. It may go up like 500 rpms but then goes down again while I'm still holding down the ...

      Very well could be a timing belt that has stretched and moved, Need a bit more info about the mileage of vehicle and known maintenance performed, also is the check engine light on? If so you could have the trouble codes run.

      I am told it has a timing chain and they don't go bad so soon. It has 118k miles and I've canged the oxygen sensors and plugs. Previous owner changed air intake manifold and radiator. The check engine was on for cylinder one misfiring which is why I changed the plugs and also for possible bad oil control valve or possible bad engine control module. After maintenance no check engine light is on most likely because the battery was disconected so just waiting for it to pop again

      I apologize, you are absolutely correct on it having a timing chain,pre-2000 had belts. Ok it is slightly possible a chain tensioner problem, or even the throttle body intake. Good Luck

      I would suspect an ignition coil went bad, has happened to me. Driving down the road to work then bam no power steering no power brakes. Have it tested first. If the car kind of sputtered before it shut off, usually its fuel related, most likely fuel pump.
