stalling problem?
 

I just got my 91 GT w/ T-5 back two days ago. It just got a full rebuild w/ Trick Flow TW heads, E-303 w/ 1.7 roller rockers, Cobra intake, 24lb injectors (set @ 42 psi), Pro-M mass air meter and alot more. The car idles fine and runs great, but it likes to stall when I take it out of gear to stop for a light. As far as I know it really shouldn't be doing this. Any ideas?

Sounds like your typical surging idle problems. Many have had this problem with mods like yours, including myself. But, you can usually correct them with playing with the idle RPM. I have to run mine at around 950 rpm at idle to prevent surging. Remember to adjust your TPS after making changes to the idle screw, and disconnect your battery to clear your processor. Check that your throttle body is clean and I assume your mass air is calibrated for the 24 pounders.

Hope that helps some...
