i dont know much about carbys so i cant help ya out... u havnt got any kind of sensors n stuff in there eh? i would say IAVC or FITV or fuel filter or fuel injectors. :)

Check the vacume hoses as a start - I'll see if I can track down some info other than that, but it's a bitch as the USDM Haynes manual doesn't cover the twin-carb. Hoses are a good place to start though. I have a feeling that the ED6 etc have an ECU that controls air-flow... ah stuff it - take it to Hanny's, Robbie or Peter will look at it and tell you what's up in seconds :)

fu*k it i am not goen to spend any $ on it coz i am converting the engine in January
but cheers anywho...if u find anything else out dont hestitate to let me know :D

they do have an ECU, when its carring on and fluctuating unplug the EACV valve two pin connector and it should stop hunting. if that is the case try to clean the eacv or replace it.

If its ECU, chances are you're running rich.

Give us some detail as to what you've changed in the recent past so we can commetn further

Are you talking bout wen ur car is warm or cold?
Cold, my car goes between 1500-2000
but wen warm, drops to about 700 constant.

[mytoycivic]

nah warm mate...
forgive my nievety but would my car, being carby, have an ECU?
BTW i have replaced:
- fuel filter, air filter, sparkies about 3 weeks ago
- fuel pump about 2 weeks ago

yes your car does have an ecu, look closely at your exhaust manifold, you will see an O2 sensor, on you intake manifold you will see the EACV, just unplug it when you car is running and hunting. it should stop hunting, then you know that it need attention. what type of plugs did you put in. was it doing this before you changed the plugs???

[mytoycivic]

no it wasnt...i should prob get better plugs...these ones were like $10 each

[ECU-MAN]

honda and champion plugs dont go to well together, NGK/denso are the best, did you put champion plugs in by any chance ?

[mytoycivic]

dont remember but i would say that would be the culpret (?)
if it started after i changed the sparkers...would that most probably be it then?

[ECU-MAN]

could be. just try what I said b4 about the EACV,

did you gap your plugs to 1 - 1.1mm

[mytoycivic]

got my mech to do it :D i have no time for diy
