ok, first off here is my mustang,
<img src="http://www.users.qwest.net/~mendezralph/Mustangsmall.jpg">
it's a 67 coupe with a L6 200 and a c4 tranny. The problem I am having is that it runs fine when it neutral or park, but as soon as I put it in gear, the engine performance suffers and it sounds like it wants to die. put it back in neutral, runs like a champ. also it has died when it has been in drive, especially when coming up to a stop sign. Anyone have any suggestions on what to do? I just rebuilt the carb, it's a Ford 1100 1bbl with automatic choke. Any help is greatly appreciated.
