Right, bug wrx all standard for the mo, the idle is a tad irratic, could this be down to a tacky flea bay chav valve thats fitted, and yes its on the to remove list
if its not that im assuming the idcv needs a clean/replace.

any thoughts cheers ,,,, steve

 

Check for air leaks and refit the standard re circ if you have it. If its still the same then clean the idcv.

 

i have checked all the vac's ect and all is well, i have ordered an oe valve as the car was bought with the chav horn on it, any tips for cleaning the idcv, i have never taken one off as yet, cheers

 

I'd start with the cheap DV.

 

yeh, that was my first thought tbh, oh well re circ in the post
