Sensor?

[wolfheads]

I have a 1994 Mustang gt 5.0. It just started doing this today....It cranked up just fine as always but when I put it in gear, (automatic), it sounded like it wanted to bog down and it died. Reverse or drive. It did it in both. But it doesn't do it every time. Any suggestions?

Thanks

Simplest suggestion is to look for vacuum leaks, make sure your tune-up items are all tuned-up. After that, using jrichker's 'surging idle checklist' (even though this isn't surging idle but stalling) will help track things down.

Thanks. Very helpful.

Yes, a lot of people miss or skip the 'surging idle checklist', because they don't have a "surging idle", It covers a whole lot more than just idle problems.

Now that you mention it, I've noticed that my AC vents stopped working. Just the defroster is working. I don't know if that would be a result of the problem.

One of your accessories may have gone bad.

If your DF is working but not ac, good chance you lost your ac condenser.. happens.

These cars break shiit all the time. Best best is let it idle and make sure all is working.. and nothing is hanging up, or smoking, or doing something that shouldn't be happenning.. obvious is obvious...

The AC is working, it's just coming out the defroster vent.

Vacuum line.
the system is made to default to defrost if it loses vacuum.

I corrected the vacuum line under the hood once before to correct the same issue. All is well there. Is there one that needs to be checked under the dash? Location?

Yes, it comes in behind the glove box iirc, travels to the havc control knob. I think there is a vacuum canister behind the inner fender panel in the wheel well too. The plastic lines under the hood can get brittle and break, I would look there again. If no leaks found there you may need to borrow a vacuum pump, the selector dial is also prone to leaking.
