what have u done recently to it? last time u changed plugs, plug wires cleaned ur injectors, distributor, etc... did u adjust ur timing at all? or have u just left it alone? give us a run down of what mod's u have and what ur car condition is in and we'll be able to give u more to work off of,turning the idle screw up in the mean time is a good idea to avoid the car dying out on you, mine was acting up recently dying at stop lights but i cleaned the injectors took off the fuel rail and cleaned it all and its fine now.
