i have 2000 civic coupe with GSR swap along with P30 ECU. my problem is the engine normal idle 900 rpm and my car idle 500 rpm. when i'm shifting between gear 1 & gear 2 & 3 etc... it's going down fast and the vtec working @ 5800 rpm when shifting from gear 3 to gear 4 the vtec wont work cuz the rpm drop quickly.

another problem when the A/C ON the compressors dosn't work cuz the rpm drops to 500 or less.

i know my problem is with shity idle but what do u think the sulotion are ?

 

please help

 

62 people no one will help me ??

 

my first inclination would be to bump the idle up on the throttle body to see if that helps any, it may have just been set incorrectly.

 

set the screw under the tb and/or idle adjust. Doesnt seem like a major problem.

 

set it with service connector jumped or your ECU will return to factory settings ... after a short while (downwards of 20 miles drive)

 

i'll do what guys you said, after that i am gonna clean IACV & FITV and adjust it ..
will see

thanx all for the help

 

Any CEL codes? A dirty FITV would not cause a low idle.

 

thank u guys for your interaction with me, but unfortunatly my broplem is continue to exist even though i cleaned the (FITV) & (IACV) what do u think the broplem is no thing changed....

 

Amaq i'm having a similar issue with my stock D series, I cleaned up my IACV yesterday and my can is idling around 500 but this doesn't change if I turn on my AC..so the car is compensating for that.

I'm going to try adjusting the idle screw and maybe you should as well and we can report back the results.
