hello [people
my abf will sometimes idle spot on at 900rpm and not move at all but the car seems to shudder and seems as if its idling roughly.
other times there is no issue what so ever.
is this the ISV??
its not bad (yet) but just wanna know what could be wrong or going wrong
thanks

With or without AC?
-
no A/C

I would give the isv a clean mate, take off the hose, undo the Allen bolt holding it on and pull out, clean thoroughly with carb cleaner, if you can leave it connected up and clean with it buzzing away so it's more effective
-
I'd run a bottle of injector cleaner fluid through as well

cheers guys, ill try it over weekend :smiley:

what engine (code please) have you got?
1.8 aam, abs, adz are notorious for having broken gears on throttle idle mechanism... which would give you exactly the symptoms you have now

I guess ABF

d'oh... yeah i'd go ISV then.... other option would be potentiometer on throttle but that'd cause otehr issues too

You could do a quick check to see if your switch for throttle valve is working properly. Its a basic open/close switch, check with a multimeter. If that one is broken you can get strange idle. Since it tells when the throttle is shut and when to idle.
If it's broken you might have a problem since the dealer canceled them 2007 - But i've come to understand, UK is where the ABF parts are :D

Did you port that throttle body I sold you mate because if you've gone too far on that you'll blatantly going to get idle problems.
-
didnt get round to checking all this yet. i drank to much beer lol.
have to try in the week at some point.
yeh having read some more i think its the isv.

yeah i did man but didnt take to much for exactly that reason. i was constantly putting it back on and checking as to not messs it up

cleaned the isv today. it was very black and gunked up. although it hasnt really made a great deal of difference.
one of the vacuum hose near by is split tho so i will replace that and may as well replace all of them while im at it which should help.
to get black or something bit more fun in colour tho??
