At times it seems like my car doesn't want to start... It will try for a little bit to turn over until it finally does, but then runs rough. it has an AEM EMS and an MSD ignition w/ an external coil, but no box. After its started, while sitting still at an idle, the RPM's will jump from 1k to 1.5k and it wont stay steady and also sometimes will drop down to 500 and die... I am going to get the EMS tuned better but I was just wondering if there would be something else. thanks
