B18C Type R Troubleshooting

hi everybody
currently im driving a JDM 00 civic sedan swapped with Integra Type R
B18C engine.
most parts are stock other than Mugen twin-loop exhaust system.
VTEC kicks in well at 5800rpm and it has made my driving an addiction.
=)

however, there was a slight problem.
after ignition, when idling the rpm goes lower than 1k rpm and the
check light is lit.
i have to turn off and start the car over again and add in a little
throttle balance over 1.5k rpm to heat up the car.

this only happens when i left my car undriven for hours or cold start.
so if there's anyone who know what this problem is, please kindly
share ur opinion with me.
thanks.

hope i can troubleshoot it a.s.a.p =)

 

what is the error code recorded by the computer?

 

it doesnt show
that's why it's troublesome =(

 

if the c.e.l. is activated, you have a code.

 

or, since it's now wednesday, call 800-873-7073.

 

i have my mechanic checked up my car, it's the throttle body problem
after cleaning it up the idling goes well again =)

but i doubt how long it would last before the throttle body gets dirty
again... hmm
