95 toyota camry station wagon

Once again, the first port of call is the IAC valve. The idle air control valve controls the idle speed of he engine. After some time it can become sticky in its operation and can be cleaned. Here's Daniel's description on how to do this job. He's done it plenty of times with success>>

------ Daniel's IAC cleaning method:

If you go to Redline's Internet site they have detailed technical information regarding the fuel system cleaner including graphs and apx.

4 pages of text. Should answer any question you may have. All you really need is Tri-Flow for a newer IAC valve. Just spray some into the opening on a cold engine. How does the novice find the IAC air intake? Easy. Open the hood. You should see the battery right in front. Just behind that is the air filter enclosure. Follow the air tube back as it curves around to the left. It terminates at the throttle body. You'll see a wheel with cables going to it in front. On the '94 it's just behind the distributor that has the spark plug wires. The wheel with cables is the throttle valve that moves when you press on the gas pedal. The purpose of the idle air control valve is to route air past the closed throttle valve at idle, so the air intake is in front of the throttle valve inside the throttle body. You need a 10mm wrench to loosen the clamp holding the air intake hose

- a fairly large diameter black plastic hose that connects to the throttle body. You're going to have to turn that hose clamp bolt a lot, so it is easier if you have a ratchet wrench or GearWrench, but actually any

10mm wrench will work. After the clamp is loosened, use both hands to simultaneously pull back and twist and wiggle the connection to release the air hose. Then pull it over to the right (windshield) side of the throttle body to get it out of your way temporarily. Then look inside the throttle body. Right in front, at the bottom, you will see a rectangular shaped opening. That's the air intake for the idle control valve and that's where you spray a small amount of Tri-Flow. That's it. You're done. Pull back on the air intake tube and press it back into place. Tighten the hose clamp. It doesn't have to be over tightened, just firm - snug - use light pressure on the end of the wrench until you feel it stop turning, then don't force it, just apply moderate pressure such that you've reached the natural holding force of the fastener. One can of Tri-Flow will last for years, and one application should be good for around a year. Perhaps after you've accomplished this, you may be emboldened to try other maintenance or repair procedures, but at least you'll have this one done. ====================== By the way, if you really want to see a picture, the Haynes repair manual for your '94 has a photograph in the Fuel section of someone spraying carburetor cleaner into the throttle body so you should be able to see the IAC intake opening there.
