i'm having issues with my car, i'm out of ideas on what it is i hope someone can help me. whenever i drive my car for awhile and the motor is warm i turn it off and let it sit for a couple of hours but after that i start if up again and drive it seems like the butterfly is stuck! when i step on the gas it hesitates and jerks, but when i let off the gas it seems like the butterfly is sucked and doesn't wanna go. i've cleaned the butterfly with throttle body cleaner and nothing, i replaced the sensor behind the intake manifold and nothing too. so please help me if you know what it could be? thanks

 

Does it take a few second then go? Kinda rumbles around then your good to go or what?
If so it's the same problem I was having and one day it just stopped. Still does it every once in awhile but I just kill it and start it back up and I'm fine.

 

yeah sometimes when i turn it off it still does it, but most of the time it's ok cause i don't really drive it as much, and yea it takes a few seconds then go. everything works fine other then that, vtec, and coolant is fine. it gets worse when i down shift and hold it at a high rmp like at 5k or 6k it jerks back and forth

 

It almost sounds like you are having a MAP or TPS sensor problem.

 

you think so? but i have no check engine light, well when i start it up i don't have any until i drive it for like 20 min. then the check engine light come on, not sure what that is too.

 

jump the service connecter under the passenger side foot well and see what the code is. there's a how-to in this forum... use it.

 

yeah i'll try that see if any code will come up
