87 with some issues

[Oblivion_RX7]

I have a 1987 RX with one major issue that has me stumped.
Starts & runs when engine is cold. But is hard to start after engine has had time to warm.
This is my first RX-7 and don't know if it's something with this model or what, but any help would be appreciated.

Hey Oblivion, wish i had more insight for you. I picked up an 87 bout 3 months back. It ran like a dog when i bought it, spitting and sputtering, not wanting to idle. Turned out to be a vacum line that some half @ss mechanic forgot to reconnect after changing the clutch? I guess he tried to get the bellhousing bolts on the trans from the top instead of from under the car and moved the hose and forgot about it? Anyhow, i check all your connections and hopefully someone with more knowledge than me will stumble across this and help you out
