1998 Toyota Camry LE 4Cyl2.2L - Engine
why does the engine go off?
i have a camry 98, second owner odo 166000. for the last few years i have had this problem - after reducing speed, even by just releasing the gas pedal sometimes, it begins lightly irregularly shaking back and forth, which gets stronger before i stop, and the engine goes off itself. then it does not start but after some pumping the gas pedal, it starts and runs again like nothing has happened. years ago it used to do it rare - once every two months or so, but for the last few months it has been doing it too often, and today the motor icon on the board went on. few years ago, when i first encountered it., i asked a mechanic ,who could not figure out the problem- maybe engine problem or a dirty tank he said. he checked the engine and said it is alright, back then.
i started the car few minutes ago, with no problems, but it sounds broken through about equal intervals, and the arrow on the board moves between 0 and 1.
what do you think my problem is?

    i don;t hear anything from behind. there are valves, though, making a regular noise everytime i press the gas pedal, and more frequent the faster the speed.
    is it possible to say what $$ i am facing in repair, considering it might be various things? is it possible that dirt is being sucked from the tank,? the more time goes though, the more i think it is an engine problem

    another impression - sometimes i go away for the summer and don't drive the car for 3-4 months. coming back, after charging the battery, the motor still goes on hard, like 'choking'. then it runs and does not do it anymore.

    You very likely are describing an excessively worn inner CV joint. I have run across this a few times over the years. very hard to diagnose, usually the car gets the full auto parts store thrown at it to no avail. What happens is as you accelerate the inner tripode that is supposed to slide in and out of the inner tripode housing (also called a tulip housing) begins to extend furthest outward under the hardest acceleration. The reason it slides outward is because the suspension height changes causing the axles to want to "stretch". The problem is that the outside edge of the housing gets excessively worn and there is actually place where the tripode gets stuck. when you let off the gas and the engine relaxes and the suspension height lowers and the axle tripode tries to slide back an inch to effectively "shorten" the axle, the tripode becomes stuck in that worn spot. The result is what you so gallantly and effectively described. A shaking of the chassis (and steering) back and forth with an irregular rythym that finally relaxes as your mph gets near lower speeds. Not sure what side is your cause but I would guess the left because that is the shorter axle.

    thanks for the responses!
    how does this 'pumping' the gas pedal help it? and is this dangerous for the engine? this last time it took quite intensive and fast pressing and longer than usual before it got to stay on.
    when the problem occurs, i don't think the steering shakes too. when i stop the whole car shakes actually, and sometimes does not go off.

    The next time you have an experienced tech look at the car and if he can experience this shaking which might be hard to replaicate at the time, at least mention what I said and get his opinion.

    would the fact that the engine icon is on now help diagnosing? also do you think the problems can get worse to the point the car does not start at all if i continue driving it now?

    wait... sorry for the question, is the c.v. joint refering to the engine or the chassi? because i somehow believe that the engine icon on now is related to the problem

    If the check engine icon is now illuminated, it definitely has a stored fault code waiting to be accessed. Read the code beccodes tell a story. Do not know for sure of courseif the code is related to your cause. Tell me the code number.
