my 96 z28 idles very rough when it is started and in park or neutral, but when I put it into gear the rattling noise stops, any know what it could be?
Also, after spirited driving (I'm not out there beating the **** out of it) if I shut the car off and then go to start it after a short break, the engine severly lacks power and it acts like it is misfiring, is that a bad fuel pump of what?
Thanks
