Hey, 94 integra w/ ls vtec. (B18b, GSR head&intake, crower402s, portflwo v/t) The car starts ok but will not idle on its own! I've tried raising the idle (via the screw), cleaned the IACV, checked tension on the throttle cable, timing is perfect.....ARRRGGGHHH! (frustrated DSM guy working on a honda, sorry!) Does anyone have any Ideas??? I've read almost all the archived threads about low idle, poor idle, ect. Even went through trouble shooting sections of the Acura dealership manual. Any ideas guys?

ah...rooking for help from you honorable Honda massa' techs (bump )

 

when i installed a set of crower 403 cams (mine was for non-vtec B18B motor) my idle was unstable. whenever i hit the throttle and let off, the car would drop the rpms really low and sometimes stall out. i fixed the problem by buying a B&M FPR and uping the fuel pressure, tuning this new fuel pressure with an SAFC, and also rasing the idle screw. if i were u i would try to raise the idle screw some more. on my car, the screw was hard to turn and when it did turn it only turned a little bit. i thought that this was the max position, but i could have turned it more. i needed to get more grip onto the idle screw so i took a screw driver and placed it on the screw, then hammered the screw driver on the the screw in order to get more grip. Do n this allowed me to turn the screw some more and the idle has been fine since.

 

Thats a good thought, i think i have a FPR somewhere. At this point i'm almost just considering the stock cams...lotsa little issues in tha past few days. having random knock sensor codes too. thanks for the idea, may try that.
