Well... its a shame that I think this is my 100's post here. Being that is a sad one...

I have my 1989 RS V8 TBi with auto 4 speed. When the engine fires from a cold start, it runs just fine. AFter its warmed up a bit anytime I brake, shift in to reverse, or let the RPM's dip below 600, the motor dies, and wont start back up for 10mins.

I took a video of the RPM gauge! This is what it does moments before and after my engine stalls...

at that time I got the car started long enough to get home, but I was sitting at a red light in neutral, holding the RPM's at 1500.

HELP?! Im starting to get aggravated. Its just a recent issue. I have already replaced the idle air sensor.

Check vacuum lines for leaks?

Hm... going to have to. Thanks!
