lunytnz Dies at throttle off

In the middle of a trip, the other day, my 87 died as I came up to a stop sign. I had to give it some throttle pedal to get it started. The rest of the way home, it died every time I took my foot off the pedal.

I learned to keep a little pedal into it all the time to keep it from dying.

The next day, after driving for about 10 minutes, then stopping for an errand. It started up and idled fine and has been running fine ever since!

I figure it's the IAC (Idle Air Control) valve. But, if there are other possibilities, I'm all ears!

The first thing I would do is clean the throttle body and the IAC. Reset the base idle and check the timing. Clean the MAF while you're at it.

If that doesn't solve the check for vacuum leaks.

My ‘88 had that problem for a long time. Turned out to be a vacuum leak.

vacuum is huge problems as any car ages... the hoses just turn to mush and can't maintain pressure.

I would replace all soft vacuum lines, just as a matter of maintenance.

It doesn't cost that much.

Also, check the IAC... Idle Air Control valve. Usually the #1 cause of such stalling problems.
