I had an '88 and it was the same way. Hot idle the gauge was around 1/4 or a little lower. I think there is an underlying issue causing the engine to stall.
Do some simple things: Check fuel pressure Check for vacuum leaks Check/replace ignition components Change oil, oil filter and flush the engine. Change air filter Clean throttle body, IAC pintle and assotiated passages
