I have not experienced or heard of any such problems until this day. The mitsubishi direct injection petrol engines had some issues, but never heard of any problem on the toyota ones.

Just guessing here, but wouldn't think the catalytic converter should have taken any serious damage, and suppose the check engine light will go out when disconnecting the battery.

This pic is from a different type avensis, but the engine is the same.

If not already doing so, use washer fluid with an antifreeze. For example ethanol (not engine coolant antifreeze). Could also be something stuck in the tiny nozzle hole. could be car wax or similar. For cleaning them out, use a suitable, not too wide metal wire.

Perhaps toyotas behave the same way as fords do when the battery goes weak. Could be worth checking up. Have a look here : http://www.fordfusio...ht-bad-battery/

Could be the automatic ABS brake check. Mostly happens at first start of the day, and just after setting off. The sound could be described as a very short "clonk".

Sensor 1 is pre, sensor 2 is post cat.

Does it happen every time you set off, or just once, seconds after the engine is started?

...and remember to always disconnect the battery for five minutes and leave it that way, before tinkering with airbags.

Is your car 1.8 or 2.0 litre? /Edit Saw in an earlier post it is a 1.8 litre.

Would be a tad easier if stated what model you have, but I suppose you are talking about the "2000 w plate avensis gs" spoken of in an earlier post.

You've got the 1AZ-FSE.

My impression of the 2.0 litre vvt-i is that it lacks a bit of tourque below 3000 rpm, is quite decent above 3000 rpm, and really comes to life above 4000 rpm. So something must be wrong with your car, and if it feels normal between 2000 and 3000 rpm maybe its just the fuel filter that's clogged or something similar.

If left unattended for 6 months, worst things that could happen would be : Battery being drained (recharge), Radio memory being reset (re-save settings), Drivers side power window being reset (set the max up/down position for it to function properly) And if left standing outside, maybe needing a car wash :P
