Today after work I went to start my car and it just started surging real bad and shut off. I tried to rev it a little and then it just does the same thing. I finally got the car to stay running after it warmed up but it still idles real low and surges a little. Does anyone knowwhat this could be. It is a 96 gt 5 speed with no mods except for a upr catted x pipe and flowmaster cat back. Please help this is my daily driver.
