Me again... (thunderbird stalling at lights and such)
My Thunderbird is an 8 Cylinder, 5L and while idling in drive, shakes like its having an epileptic seizure... That is why I keep my foot on the gas at the same time, then I do not stall.
My question this time is why would the colder weather help the car run better in this case, and what is the actual shaking I am feeling? And in that case, why is it shaking more sometimes than others?
Any theory on the ignition module affecting this or still a potential fuel pump issue?

We had the same symptoms with our 5.0 Mustang GT, and after we replaced the fuel pump and filter, we had the same problems. It turned out that the mass air flow sensor was bad. It runs like a top now.
