You have a 91 geo storm and it has been stalling at traffic lights from time to timeIt also stalls sometimes if you are turning a corner and take your foot off the gas peddleWhat could be wrong you ha?

try fiddling around with your idler or maybe replace the fuel pump or fuel filter.

4/5/2010: I have the same problem with my 1992 Geo Storm GSI 2+2 and have been told it's the EGR valve. Good luck finding one. I'm having trouble myself.
