1999 olds alero 3.4 starts and idles fine, put in gear and excellarte it misfires. If u push the gas to the floor it will slow down but when you let off it will pick up speed. When it quits you have to let it sel for about an hour and it might start back up, if so it will miss and shake then it will smooth out but you cant give it gas if u do it will backfire.
have the same problem?
