1994 Ford Thunderbird car dies out when I put it in gear

First thing I need to know is, is this OBD I or OBD II? Look on the information label(V.E.C.I.) Under the hood, it will say either EEC V(OBD II) or EEC IV(OBD I) And it should be a 4.6.

On the white label under the hood, it will say EEC IV or EEC V...or tell me what kind of DLC(Data link connector) it has? Under the hood? or under the dash inside the car?

This means there is no way to get the codes except to buy a cheap scantool, plug it into this jack and turn the key on, one or more codes should display, write them down and post here. It sounds like a transmission TCC solenoid stuck, but it could also be the filter fell off the pump and is sitting in the bottom of the trans oil pan. BUT it can be other things! Fuel pressure is possible too. Scan first replace parts after! Your DLC is under the glove box.

No, most common and full featured is ACTRON. But get whatever interests you, if you plan on doing some of your own repairs, buy a good one, they work on all cars sold in the USA since 96' They range from 40.00 to several thousand dollars! Depends on what you plan to use it for. Basic ones red only generic codes, enough to get by, expensive ones read multiple modules and cost a ton, and have a learning curve.
