My small turbo cos is slightly juddery at low speed,been told it could be a sticky idle control valve,it only starts doing it when it warms up,i have put on the standard airbox and its slightly better.......any help please

ajjames

mine also does this on light throttle when it warms up i have been told they all do it but im not sure this is right

Andy E

Defo something not right,so ive done the right thing and booked it in with stu at blackpool

ajjames

let me no if he finds anything is your car standard or modded

cahzz

nope its defo not right, mine drives totally smooth when just setting off or fully heated

Andy E

Totally standard apart from the k+n,ive even put the standard airbox back on,it drives ok till warm and then give it a boost and thats when it starts happening,it almost feels like a dodgy throttle sensor but surely it would happen all the time????????? Will let u know the outcome

G1EN

mines got this too. Was going it for a soon for a check up and fuel etc checked and set up to see if this cured it. So if an outcome hasnt been posted when i get mine back ill stick some info up.

If you've had a K&N on it there's a good chance that the wires in the MAF have been contaminated with oil. The usual way of cleaning is to spray the wires with electronics cleaner (some people use carb or brake cleaner but I'm not sure if these can have a detrimental affect).

i had to replace my AFM

sailorbob

After cleaning it?

adamski frst

What about on Large turbos that do not have the MAF?

I have now checked plugs,pipes oand everything is clean and as it should be,seems to be happening in all gears at about 1800/1900 rpm and is fine at other times.I did have the battery off for a while though,so is there a way to reset the ecu settings???
