I’ve been using Deoxit D5 on my guitar volume and tone pots for a while. Every guitar and music tech in any band for any genera knows about the utility of Deoxit. Well, this anti oxidation chemical works wonders for any electronics and connections. It’s safe on plastics and all sorts of different materials, I haven’t had one fail, but I’d wager that Deoxit could remedy a variety of ecu, airflow meter, and TPS issues. Anyway, I wanted to share this product. They make several different types for variety of applications. I use D5 for my applications and it does incredibly.

 

I’ll second that. I use Deoxit on all my audio stuff. It’s not cheap but it's the best!
