have you driven in socal's daily traffic commute? the car sits most of the time idling down the freeway. yes, it can be caused by driver error also but most of the time its caused by the map sensor

are you on the original clutch? it may be a worn clutch that is contributing to the issue...but it is not necessarily a problem.
press the clutch pedal and go at it again.

It's driver error. I've posted this a dozen times. Don't blame the car.
When you press on the accelerator, the car lunges forward. That causes your body (and your right leg) to move backward, causing the car to buck. Your reflexes press on the pedal more, causing the cycle to start again.
You don't even know you're doing it. Heat soak aggrivates the situation, but the primary cause is that your entire leg is going forward and back, causing the car to buck. Remember: you're sitting very low in a car with a very stiff seat and suspension, so the slightest movement of your leg will transfer the force to the gas pedal.
Solution: Cram the right side of your right foot against the carpet to the right. Let the friction between the carpet and your foot prevent you from moving your foot on the gas pedal. When you want to move the gas pedal, put the force on the carpet as well, not just on the gas pedal.
You will be amazed that the problem disappears.

give it more gas when you're engaging the clutch...and don't let your rpm drop to low when you slow down and accelerate again...or just disengage and engage again with more gas.

The heatsoaking is a known issue. I guess it's not the easiest thing in the world to get an engine to rev to 9K reliably as well as to idle in all conditions regardless of air temperature.
Generally when this happens to me I clutch in then give the engine a little rev. This solves it for me, but I don't know the reason why. I can only assume getting fresh "cool" air into the engine helps it smoothen out.

So what is a CAI. My car is doing the same thing, and no it definitely isn't driver error, or the driveline play, or my leg rocking back and forth on the gas pedal. It feels like it is going to die when this happens to me.
