Issue with my idle

I was trying to get it on video but I didn't catch it. Every time I come to a stop at a stoplight, if I have my clutch out, not in gear, it tends to drop RPM's to about 300. It'll sit at 600 no problem, but out of nowhere it'll drop suddenly like I'm about to stall out. It's been happening the last month or so. I can feel the car start to sputter a bit. Idle control valve? Gas issue? Car is on 91 Shell and VF Engineering tune IPE exhaust with primary cats. It's been fine until the last 3-4 weeks.

Thanks for any input or help.

There is a thread in the general discussion section on various idle issues. The one I've experienced was the fuel tank breather valve issue. If that is the problem it will only happen after you fill the tank. There is a DIY on replacing it.

Ok, should have done my research first. Thanks for the fast reply.

Spencer, Does it happen even more so when filling up the fuel tank? Mine was doing it really badly, (The car would stall sitting at a red light) right after fill ups. Then after it sat overnight or so, the next start-up would be back to completely normal again. Ended up being my fuel tank breather. Not too tough of a DYI either!

Yeah, well thankfully it's not too cold here. It'll happen randomly.

Yeah, it happens after that but also any time at all, haha. I'm going in next week to SSR Performance to have it looked at. Thanks for the help.
