Engine Mechanical problem
2000 Acura Integra 4 cyl Front Wheel Drive Automatic 125971 miles
----------------------------------------------------------------
I have a 2000 acura integra ls sedan. After driving the car (say 1hr or two), letting the car rest for about 30min. Then, starting the car, as soon I step on the accelerator pedal (gradually), car does not accelerate for like a second or two. After that brief pause, car then accelerate with a kick. This happens intermittently and only after starting the car.

I've replaced the fuel pump filter, pcv valve, poured a bottle of STP injector cleaner before filling up for gas. And problem still exists. However, I've not cleaned the throttle/choke as of yet.

Any help is greatly appreciated.

Might want to test the throttle position sensor it takes the place of an accelerator pump on a carbuerator-to prevent hesitation- could be a weak spot in it/out of range-

Thanks for the tip. Do you have an idea where I can find that 'throttle position sensor' on the vehicle? I currently don't have an acura repair manual at the moment, but should be arriving soon.

Thanks for your help.

Excellent! Thanks for the detailed diagram. Will post my results after investigation.
