Intermittent stalling on warm starts, No issues with cold starts. Options

[jordisonjr]

Hey guys, looking for some advice on an issue that arose on my car. Ill start off by saying its a 95 GTS (Canadian car) with a 5sfe. Motor is completely stock aside from a short ram intake, which I've just replaced with the factory air box.

From time to time, when the car is warm, it'll give a tough time starting. Ill start the car up cold and it gives no issues, drive it untill its up to temperature, and then turn the car off. I'll let it sit for 10-20 minutes, come back and the car will give difficulty starting.

It'll fire up to about 1000 RPM (regular idle) and then drop right back down to 0. If i give it some throttle I can get it to run if i hold the RPM at idle for 30 seconds or so, and then it runs and drives fine. However if I don't give it throttle it just stalls out again. This problem is also very inconsistent, majority of the time it will start and run fine, but when it does give me problems, its always under these circumstances.

It occurred once this week where i had to give it a significant amount of throttle(1/4 to 1/2) to force it to start, and then held it at idle for 30 seconds or s, and then it idled fine.

I posted this on the facebook page, and also did some researching on other toyota forums, and have a very very rough idea what could be causing this, and I'm hoping someone could provide some insight as to what could cause this. Its a difficult thing to diagnose, as it doesn't happen extremely frequently, but I'm also hesitant to drive it, as I don't want to get stranded somewhere with a vehicle that doesn't start.

Any help or advice would be greatly appreciated.

I managed to get it off. Soaked it with PB blaster Monday night, Tuesday morning before work, and after work, and then cracked them all Tuesday evening. used a #2 phillips (Or maybe #1, I don't recal) socket in a ratchet and it cracked right off.

Now when it comes to cleaning the IACV, I was reading on a ToyotaNation thread, to remove the electrical plug, and the you will then be able to rotate the valve to completely clean the inside. There seems to be a gooey gum-leak sealant between the plug and the valve itself


You can kind of see it oozing out between the connection here. Anyone know what type of sealant this is? I'd like to be able to re-assemble this after cleaning correctly to avoid issues.

Or would the better option be to go from the opposite end, remove the end cap, and clean from this side:
