hey guys my brother has got a 95 4runner with the v6 and he can't get his idle to be consistent. we've replaced the intake plenum gasket and the big hose from the aircleaner box. we can't seem to find what is making it do this and he used to have an vacum leak that he fixed but it still has a wierd idle. any suggestions? on the 88 and older truck forum the vac lines seem to be a problem but i wouldn't think that on a 95 you would need to.
