Hello,
I have a 99 Toyota Camry, 4 cylinder (160K). It won't start when the engine is cold. It'll click but won't turn the engine. If I rev the engine by stepping on the gas paddle, the engine starts but it stalls again when the foot is off the gas paddle. To start the car, I have to keep my foot on the gas paddle for 5 sec. I read years ago from this forum that spraying carburetor cleaner into the IACV would help . I tried that and I was able to start the engine today and yesterday. Is this a long term solution or should I take it in to have a check? What are the potential parts that need replacement? The batter is new. The starter was replaced three years ago.

its a long term solution. the iacv was probably stuck and spraying it out cleaned it. if this happens again, just take off the iacv and clean it throughly and it should keep working.

Can you even really clean the IAC on these cars? The last time I saw one where you could even take it apart good was on my 1985 Escort GT. It was two pieces that were bolted together, so to clean it, you could take it apart and clean out the insides really good. On any newer car I have seen. the IAC is one piece that can not really be properly cleaned like that. The best you can do is to soak it and hope for the best. That's why I don't trust IAC's much past 150K,

I would also be cleaning the throttle body.

Yep, Try to clean the Idle Air Control Valve in the throttle body

I agree with cleaning out the entire throttle body along with the idle air control valve. Here's a good DIY for cleaning it on your exact engine with dome good pictures:

Thanks a lot for you help! I'll give it a try tomorrow.

One more question. Does the throttle body need to remain open when spraying the Sea Foam Deep Creep into the hole?

Yes, it's best to clean both the front and back side of the butterfly valve inside the throttle body. One of the pictures in that thread shows the picture of a slotted screwdriver holding the linkage to open up access to the back of that butterfly valve. Take a look at that picture. Just don't stick the screwdriver inside the throttle body itself to hold the butterfly valve open. You don't want to scratch anything inside there.

Thanks Mike! Step 3 was where I found it unclear. I know exactly what to do now.
