You don't have a carburetor. The carb cleaner suggested is for cleaning your throttle body. A very good idea. To clean the TB on out Envoy 4.2L I remove it first. I can do a better job of cleaning it and don't have to worry if the cleaner is "sensor safe" or not. In 125,000 miles I've only had it off twice.
Ok I get it now. Maybe that's what they did when they said they cleaned "it" I'll find out what that is about.
I am wondering if it will still act up after I change the plugs and wires because the sensor is now dirty again since they cleaned it.
The truck sure runs better with the new fuel filter. I had no idea it wasn't running so well before. It must creep up on you and you get used to little hesitations (now mostly gone) when at idle etc. Maybe if I had kept an eye on my gas mileage I would have noticed it was getting worse, no idea. Anyway, "smooth running" has gone from "good" to "real good", so with the new plugs and wires as well, we should get to "really good". :)
Got to say this truck is way better than any car we have ever had for how little work it needs on it for the miles on it. Course it cost a bundle new, but after twelve years that puts us ahead in comparison. Too late to apply that lesson now! You can't turn the clock back. :(
