i have a 87 rx7 n/a. i went to start the car but it wouldnt. it acted like it was the battery but the volts were ok, it would go vrrr vrr vr and then dead i let it sit while i called my brother to help and he said to start it and it started no problem. then i went to start it today it did the same thing i went to call my brother went back and tried to start it,it wouldnt,waited a minute and tried again and it started but really rough and then it smoothed out. after a few seconds it was running as smooth as ever. so if you have any info on what the hell it could be please help. and what should the car idle at? thanks in advance
