car just up and dies for a split second

[90blue5.0]

I am having a problem. '90 GT with 5spd.

When driving it is like the car just dies for a split second. Almost as if the motor looses all power from the coil and just stalls out. It is only for a split second then normal again.

It does this two or three times after I start driving, after it is run for a while it doesn't do it anymore.

Does anyone know what could be causing this? Does the coil die slowly like this? or could it be something else?

So it dies and restarts on its own and once warmed up it no longer does it? Does it die suddenly or sputter a little and catch?


My truck does something similar when its cold but what its actually doing is flooding out. When I give it any gas at low RPM before its warmed up it floods, stutters, dies and catchs itself. Once its warmed up the problem is non-existent. It only does it to me at very low RPM (usually taking off from a stoplight or something) and when I have the RPM's tacked up a little and let off suddenly.. When it drops back down it'll flood a little.

i've heard alot of stories of 5.0's having this problem, and then it goes away after warming up, hell, even mine does it occasionally.

Never heard what people have done to fix it, just live with it i guess?

it isn't when it's at idel, it is always while driving anywhere above 1000RPM. Gives no warning just like a really bad hick-up then fine again.

I tryed checking my codes but for some reason my CE light wouldn't flash. I will have to use a voltmeter later today and see if that works.

i have had that problem before....NEVER gave any codes....hasnt done it in a while so i have not a clue what it could be

If it did it after it warmed up I'd say TFI, but only when cold is a mystery to me...

94-95 Mustang stalls

I have had a problem with my mustang dying then restarting. During normal driving the RPMs would drop
to 0 then since its a stick shift would start back up, but if this would happen at a stop it I would have to wait approx 3 minutes to restart the car since in would not fire back up
any sooner. After many hours of troubleshooting I replaced
the distributer and it never happened again. It was the
stator mechanism on the distributer.

Do you have any sort of MSD box? My 95 did exactly what you're describing, I could actually hear the exhaust pop when it did it if I was listening close enough.

Bypassed the MSD and it went away.

the SN dizzies seem to have some issues (like it is ideosyncratic to them).
