iac valve

[bucksta]

how can i stop the iac valve from blocking up,i clean it and it lasts for two weeks then gums up again,any sugestions

Two wild guesses:
I am totally unfamiliar with this problem but I'd assume that it blocks up because of crankcase blowby fumes carrying oil /crap thru the engine breather hose to where it goes into the inlet manifold. Due to worn engine with excessive blowby.
Or it could be coming from an over-oiled K&N air filter.

Over oil K&N filter is probably the go, i ent a bit too hard core with the oil .. LOL ..

Make sure everything is vacuumed up and no leakage i guess.
