Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck

having done Toyota parts in the past, that part number sounds like it is --maybe-- actually the Nippon Denso electrics component supplier part number for the part, rather than the Toyota replacement part number. Denso numbers often had part numbers grouped 5+4 like that...Toyota numbers are almost always 5+5 part numbers

Make sure the shift lever on the transmission is actually shifting the shaft that selects the gears.....Something is slipping where you installed the bushing.....Check for proper cable adjustment....Apply the E- Brake while working with cable to prevent accidental runaway........

sounds like the water is the culprit I think you should check your coil boots and spark plugs reset the computer by turning on the key to on position take off negative terminal on the battery leave it off for 2 minutes put it back on and the light should go out do you have a code reader it should tell you the code for your problem

I would think factory installed, but just look under the hood for a box with an alarm, key company on the box.

The best way is to ask a dealership[.

Yes - ABSOLUTELY C_maina,

Here in the USA places like AUTOZONE
(personal opinion = yuk) do FREE readings...

("FREE" can be pretty costly).

Typically giving them (A-zone) the OPPORTUNITY to sell
new OXYGEN SENSORS... (the intellectual equivalent
of buying a new THERMOMETER because you have a fever (the "NEW" oxy sensors TYPICALLY complain as well as the old ones...

this is a suggestion I would recommend SKIPPING...

((at least not BEFORE Sherlock Holmes ... has eliminate EVERY other possibility (like throttle position sensor: TPS)).

Your car is the right age where your trouble could be anything from collapsing catalytic convertor/muffler, or any over fueling condition...

My very best suggestion... See if you have any EXHAUST shops that perform "FREE" READS...

Possibly bring those "reads" back here for another
(better ...more detailed) FIXYA answer.

Cross check their PARTS PRICES with your available sources on the internet (so at least you can negotiate a BETTER PRICE).
USA exhaust $$$...

Hope this helps
