my 02 envoy has an slight hesitation off idle when hot, and sometimes idles a little funny. It drives me nuts. Ive put new plugs in, cleaned the TB, ran injector cleaner through it etc. I noticed my CPAS plug had oil dripping off it so I decided just to order a new solenoid. I got the old one out and to my surprise it was pretty clean. The screens werent dirty but it did have some sort of plastic covers on it the new one didnt have. It looks to me like they are just there to block off certain ports on the solenoid. Is this maybe an old style of sensor? The new had all the ports exposed. It started up fine so I guess its ok.
edit..nevermind..im an idiot. Looks like they changed to a spiral spring to hold the screens in, the old one had plastic pieces holding it in.
