It is usually on the rear valve cover and looks like a multi-layer disk with rubber vacuum lines coming out of the side. Disconnect lines two bolts that hold it on. carefully use coathanger or similar object to scrape carbon (often white powder substance) out of the two vacuum outlets. then use an air compressor to blow out the rest. doesnt need to be totally clean as new but enough to let the valve work.

Clean the throttle body.
Usually map sensors have to be replaced and cannot be repaired.
It depends on how much you want to spend. Common parts are fuel filter, air filter, clean throttle body, clean combustion chambers, replace spark plugs and its wires.
Use the fuel brake cleaner or throttle body cleaner.
The thottle body is connect to the plantum right in front of the air filter housing the throttle cable is connected to it.
Open the hood in Camry 07 LE 4 cylinder, beside the air filter housing you will see the MAF sensor with a connector. Open two screws and clean with only CRC MAF cleaner and put it back you should see the difference now. Shuja Zaidi
I would check the air filter first. If the filter is clean you need to clean the throttle body.
Yes the 1997 Toyota Camry has a metal screen filter inside of the transmission pan on the bottom of the transmission, you will have to remove the bottom transmission to get to the filter, because the filter is a metal screen you do not have to replace the filter, you can clean the filter and reuse it
Remove it, and throttle body carbon cleaner. Make sure that the valve can be moved easily.
First off you must drain the tank and then remove from the car. Cleaning can only be done with it separated from the vehicle.
