still having this idle issues... gsr block with b16 head hondata p28 s100...
no fitv

the problem is when warm the motor idles a little rough and occasionally drops rpms then picks itself up, sometimes stalling. it will start back up right away.
something i find unusual is when i hold down the gas pedal in neutral it surges lightly.and when i try to set a base idle it surges even with the iacv disconnected.
i disconnected the tps and it kinda steadied at a higher than usual idle of 1200... wondering if that is normal?

other than this surging the motor runs strong and only happens at low rpms

i cleaned the iacv, replaced alternator, replaced and calibrated tps.

tomorrow i'm going at it again, going to try adjusting the throttle plate stop screw (it's been messed with before). help will be very appreciated.

 

what year car is this in and what injectors are you using?

 

it's in a 98 civic... running 450cc injectors

 

Ive been haveing this same problem, found that when i push the brake sometime the rpms drop so low the car sounds like it going to cut off. releasing the pedal kicks the rpms up.

was gonna say i had a similar problem on my b18b in my 98 civic because i put the y7 injectors in instead of having the B-series (y7 are 190cc not 240cc like the B-series)

 

does that too on a ful electrical load... dimming lights feels like its going to cut out... i changed my alternator already.. kinda helped a bit... thinking of getting a new battery and maybe a new iacv... more help please
