So I just bought my 89 galant and it drove great for about a month and a half then started having issues where it started to jerk while in gear and eventually died I took it to someone they firmly believed my issue was in my batter starter and alternator and being it was an older car I had planned on doing these soon anyway. So I switched out all three and it began to start just fine then the idle dropped drastically and now when I drive if I hit the clutch the idle hits down to almost 100 in most cases it dies and then won't restart without a jump and this is with new battery and everything installed what could be wrong???
