Probably mass air flow sensor cleaner. I would guess its the most sensor safe cleaner.

I usually use a powerwasher and if it survives then i don't have to change it.

Soaking the sensing part of it in gasoline overnight then letting it dry after that might work.


The quicker fix is to just replace the damn thing. I am usually one to try to fix before replacing, but when it comes to contaminated sensors, especially o2's and given how largely inconvenient their access location is, dealing with excess heat and waiting for cooldowns and heat ups to see if it works, etc. I'll just replace the stupid thing, cry a little about it but move on with my life fairly quickly after that. Lol.

The gm parts websites have them for descent prices now, think they're around $68. Wanna say they used to be around $120, so have come down in price. That's upstream o2
