Alright I have a 2002 S2000 with 103,000. After driving the car and starting it again I press the pedal down and there is no power like a bog, then it jumps ( like a jolt ) and it is perfect and I never have that issue while driving. This never happens on cold starts! Any ideas!?

Hmmm....could also be TPS?

I get no check engine light, but Like I said only after the car has been start, I take off in first and it is like a "bog" then I just it a little more gas and JOLT boom it good.

Just started happening recently? How hot is it? Had this car long?

Do you have an aftermarket intake? Sounds like heat bog, especially now that it's hot outside.
TPS rarely gives a check engine error. At 100K miles, the O2 sensors could use a change as well...

what happens when you unplug the map sensor and then drive the car? Also, if you go WOT does the problem clear up?

It's not because of the heat, it did this when I bought the car. I don't have to give it WOT, it ony happens after the car has been driven. I get back into the car start it, idle 110%, so to take off feels like no power, I push down a little more get the jolt and I am all set. Car is 100% stock.

Ideas....?

Have you done what was suggested and unplugged the MAP sensor and drove the car?
