2004 S10 Blazer Code P0101

[SpecialK]

Was wondering if anyone had any information on how to fix this?

Check engine light only comes on when accelerating to get to highway speed. This is the info I get from the code reader and Innova's HSOforum:

You can buy some MAF "Mass Air Flow" cleaner I would give that a try. It's right before the throttle body and has little wires going acrossed it that senses the amount of air flow going through it. Some times they get dirty over time and need to be cleaned.

Thanks, I was wondering if that was the issue.

Another thing that works well is a q tip, and rubbing alcohol, just dip the q tip, and gently clean the heating elements on the MAF.

She may have gotten off easy (and I may have gotten out of work) turns out her air cleaner hadn't been changed in a while and was extremely dirty. The place where she normally has her oil changed either hadn't been checking it, or didn't tell her it needed to be changed.

Or they had been telling her and she told them she would have her Husband change it and the message never maid it to you. I see that one play out several times a year.

Lol, I always tell my wife to just have the guy note work that they think she should have done like Wippers, Air Cleaner, Injecter cleaner, Trany serv, etc, etc on the bill and I will take care of it!

I can definitely see that happening but the GF is really good about letting the folks do what needs to be done. The normal place she takes her vehicle to is not a regular repair shop though, it's the service guys at her work, hence the reason they probably never checked it and asked her if she wanted it replaced.
