Wow, I had to read your post three times to know what you are asking. Tee in a fuel pressure gauge to see what reading you get when the rpm drops. Check for vaccum leaks would be the next thing to do.

Sounds like a fuel related problem

Alright so my 87325 with a swapped 88m20b25 just rebuilt the head and replaced all seals and gaskets on the whole engine and tranny and its been running great but now lately its had some idle issues but a little different then normal e30 idle problems. So when i start her up she runs fine until it warms up ill be driving and as soon as I take my foot off the gas and let the clutch out the car just shuts off I have to stay on the gas to keep it running or if I slowly take my foot off the pedal until the rpms hit the idle speed and it will stay on then if I give it gas and just let my foot off normal it will some times drop to 500rpms then jump up and down then die again. I checked the continuity on the tps and it seems fine I dont know if its sticking some times I was going to clean it and I got a new temp sensor a new cps my next guess was the icv was sticking or getting stuck open or closed I dont know I was planning on getting a new one as well but I would like some input. Also before it started to just shut off it would drop to 500 rpms then go up to 1400 rpms then back to normal idle when ever I take my foot off the pedal so any input would help thanks.
