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.

Those are kilo ohms, so x1000 on those numbers. So 2-4 kilo ohms, or 2,000-4,000 ohms.
