Hard to start at times

Here are the symptoms I have been experiencing:

-service traction light is on (not all the time (It comes and goes).
-shaking.
-stalling at low rpm's (in park, at stop signs etc.).
-misfiring in cylinders three and four (three being the worst)
-when I first start driving and I shift from reverse into drive, the car will jolt forward hard. Like it feels like I'm running into something. This only happens when the service traction like comes on.
-it can be hard to start at times, where I have to hold the key for a few moments until it gets going.


Any ideas? I have gotten so many different ideas, but none that seem to conquer all the symptoms. As a side note, I had gotten a tune-up a few thousand miles back. So the plugs and wires are new.
