My old S10 has over 200k on the clock, but every once in a while it decides to spark knock when I start it cold. It also has a slight knock when I take off in city driving. In the country, where I live, it's fine. There also seems to be a variation in the power. I've changed cap and rotor and plugs. Has anyone had any experience with the EGR valve?
