It's on the side of the throttle body. On our V6 I unbolted it and pulled it back from the TB to hose out the guts. On the I4 I believe there is a square or triangular hole in TB into which you can spray cleaner. A search for IAC should turn up more specific information.
You can download a manual here which should provide some additional guidance... http://oregonstate.edu/~tongt/camry
^ did you reconnect your maf properly? did you damage any of the wires? double check...the no-start condition will be be due to your MAF readings at the ecu
the wires can't really get mixed up per se, but with age, people have been known to damage their maf wires since you may have to yank on them a bit to get them disconnected.
but this may not be the case though as well
did you actually take your MAF off to clean it? or did you just spray the electronics cleaner inside your CAI? not sure if it would make a difference, but you maf seems to be sending no signal
I Spayed Inside But Isint The Spray Safe...It Shouldent Have An Effect Towards It Or Can It????I Stuck I Hope I Can Get My Baby Running Again....Will It Be Expensive To Fix...
on a no-start condition, you have to check three things- fuel, spark, and air....or bad sensor readings
it could be something else as well, but it's doubtful (or at least very coincidental) if you had just tried cleaning out your maf for it to be something else
