Can anyone let me know if there is any way to stop erratic idling without taking the icv out. I've read about using carb cleaner in the air intake, will this work? if so, how do you do it? Also what is the best carb cleaner to get. I had a look today and saw STP and Wynns. Wynns looks better, what do you think?
i bought wynns carb + choke cleaner (purply blue can) for £4, just remove the idle control valve and spray it inside it, watch the carbon residues escape and keep spraying until the black stuff stops coming out. A squirt of WD40 to lubricate and expel moisture. Refit and bob's your aunty's uncle!
Its only two screws,external torx on mine,may aswell get a new gasket from vaux just to make sure it seals,they are only about 50p.
Dead easy job,if it is easy to get at,on my corsa gsi you have to take half the inlet manifold off!
