Ok, I was sending my sister to school and when I was stopping and going over the speed bumps my car seem like it was bogging and wouldn't pick up. I've only had this car for a month with 93,xxx miles. It did this two times while clutch-roll-clutch-roll- and then gas. Later down the road I WOT and it seemed fine with Vtec and all. I was just wondering if this is normal or what is it?

Map sensor - You could try the "map whack" to clear it up.

Dirty Throttle body - Get some intake cleaner and a rag to wipe off the throttle body.

Heat soak - Not much you can do for that. Lower temp thermostat, fan switch, and higher pressure radiator cap.

ok, imma try the map whack and see if it help. This problem is not consistant. Only heavy stop and go and thats only sometimes too, but red lights with clutch balancing is fine.

I use to have this issue in my car too. Was very inconsistant. After the map whack it seemed to have cleared up a little. But the problem hasn't occured since putting in Mugen Thermostat, fan switch and radiator cap.

The map sensor sits on top of the throttle body. Take the plastic end of a screw driver and give it a few gentle taps.

If you stop and go you must leave it in gear untill it idles. For insistence frist gear at low speeds, ride it till it drops down to idle 1k for most cars and the crap will not feel like crap. Same with bad idling when coming to a complete stop while car is still in motion let's say 40mph in 5th and or 6th gear, I'd use engine braking with third (rev matching if wanting to) until engine rmp comes to an idle, or you could go with 2nd gear... And so on... I read this on a forum online somewhere and it seems to have fixed some of my idling issues though after installing test pipe with cat back I'm at a lower idle, just under the 1k mark, and sometimes at the 1k mark?
