every time i fill up my gas tank n than go to start my car, it idles like crap (sounds kinda like a v8 with a big cam) n shuts off if i don't give it a lil gas for a a minute or so. Happens sometimes too when i'm drivin around for a while, stop, n turn the car off. When i try to turn the car back on it will idle right but than will just shut off and do the same as described above. Car's a 2000 em1 with a obd1 gsr motor, skank2 IM, ctr cams, walbro fuel pump, etc.............
