Ok i dont know whats going on with my car but when i first start it up its missing the tach jumps up and down and when i take off its sputtering and jerking but once the car gets warmed up it runs like a champ anyone have any ideas on what this could be....thanks guys

 

do you warm your car up or just get in and go? if it's cold out you should be waiting a while to drive.

 

well the only two times it did it is when i took off right away.......cause i was in a h urry but its like 50-60 degress up here

 

50-60 degrees is warm for a person,, but when a car puts out temps that are over 10 - 20x that hot within minutes, 50 degrees is cold. you should always let it warm up to over 100 at least, problem solved

 

sounds like plugs fouled and then clearing out once it warms up. Let it warm up before you drive it even if it is 60 degrees

 

My car has done the same thing im pretty sure it is due to a bad crank sensor, even if its cold it shouldnt do that
