There is a solenoid called an idle air control valve. It may be acting up or need cleaned. There may be a vacuum hose that is cracked or damaged thats leaking. Otherwise, if it has set for any length of time with the battery out of it or if battery is dead. The idle will search up and down while the computer relearns idle properties. This will go on for about 15-20 minutes if your battery was dead or unhooked. Hope this helps.

SOURCE: find get at the wire and plug for the oxygen sensor on 2001 toyota camry 4-cyl

Unbolt the pass side seat (only 4 14mm head bolts) and lay it back. This will give you the room you need to pull the carpet back from the console area and get to the plug.

SOURCE: Where are the spark plugs on a 2007 Toyota 4 cyl.

Just follow the wires from the coil pack mounted on top, there are 4 of them, they will take you to the side of the motor where the spark plugs are hiding. Hope this helps.

SOURCE: 1998 camry 5sfe engine, surging at idle

Check for air leaks in the vacuum pipes in and around the inlet manifold, they have a habit if going brittle and splitting.
Another possibility is the temp sender , if the ecu thinks the engine is too cold it will compensate causing the engine to " hunt". This can be something as simple as a worn radiator cap seal letting air into the cooling system and tricking the sensor.
Hope this helps, Marshall

How to clean the throttle body and the idle air control valve


I typically remove them to clean but they can be cleaned on the car. Get throttle body cleaner from the store and spray all over. Manually open the butterfly valve and wipe after. I would take the idle air control vavle off to clean it.

You might need to adjust the throttle positioning sensor or better yet only have to clean the connections.
Try cleaning all the connections you can find around the throttle body.
a quick shot of carb cleaner might also help while youre at it.
Good luck,Gary.

It is app .044, but most of the new plugs come pre-gapped, you don't have to touch them. Some of them don't have anything to gap. Just a point and a rim. Hope this helps.

Idiling Issue


I had a similar problem with my 1999 camry 4 cyl except the check engine light never came on. When engine warmed up if I would stop at a red light it do almost exactly as you described. I would clean the throttle body and definitely the IAC (Idle air control) valve. Check out this link http://rav4world.com/forums/viewtopic.php?t=11555

I cleaned mine a little differently than this link. I used throttle body cleaner and sprayed inside the IAC hole. The spray tube would not reach down in the hole so I used a small piece of aquarium air line to extend the sprayer. I did a few 3 second bursts and then let soak about half hour. Reconnected air intake hose and drove it a few blocks and repeated the process. I replaced sensors, had injectors cleaned, new plugs etc. and nothing helped until I cleaned the IAC. After cleaning I would have the injectors cleaned.
Hope this helps.
