i have a 94 gt. it was bone stock with the exception of a cold air intake and an x pipe and bassani mufflers. today i swapped the intake out for a 95 cobra upper and lower intake. i also installed 24lb injectors a pro flow mass air off my other 93 mustang that is calibrated for the 24lb injectors. also did a kirban adjustable fuel pressure regulator. the car starts right up and runs just fine for a min or two revs up good goes back to 7 or 800 rpm for idle and then will just shut off like someone hit the key. i know these cars computers are touchier then the 93's but i have no idea what could be wrong. this isnt my first time around the block with a mustang but it is for a 94/95 car. anyone have any ideas? still has smog pump and there are no vacuum leaks. and i checked the timing with the pill out and it was at aout 35 degrees which seems way high to me but i dunno what its supposed to be hope someone has some info thanks in advance oh and also the car had a big vacuum leak which is why we decided to do the swap since we were pulling the intake anyway. have that fixed now but now have this problem
