When the weather is cold (ie Georgia cold around 40F) and my car is in Drive but my foot is on the break my car will shudder and then die.
<br/> I can avoid the dying if I take the load of the engine by putting my car in Nuetral /Park or if I can take my foot of the brake and start driving.
<br/> When the shuddering is happening my headlamps dim and the RPMs indicator bounce from 1000 to 2000 RPMs, the needle bouncing and dimming are synchronized.
<br/> The car will start up again immediately after it stalls.
<br/> I took it to the mechanic he said he couldn't find anything but he tuned my idle to see if it would help... it hasn't.
