Odd Sounds that’s I cant explain??? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Been having issues with the car recently has the 3.6 V6. First it had a miss fire in cylinder 5 that got fixed. But started throwing a code that I was running lean on idle bank 1 and idle bank 2. I have a new MAFS on the way but also read it’s worth a shot to clean the old one and after attempting to clean it, it started making this noise that I’ve never heard before.

Checked for a Vacuum hose leak and couldn’t find one. Is the mass air flow sensor the issue here? Or an O2 sensor or what. All help would be appreciated since I’m at a loss now on why to do. (Video Below)

We're gonna need a better video than that - what noise are you talking about - I assume not the thumping?

I am talking about the loud thumping yes. I’m worried absolutely it keeping it turned over too long Incase it damages anything

Ok that noise does not come from cleaning the maf unless it's firing out of order. Did you drop or lose anything during the cleaning? Start by removing the plugs, turn it over by hand, and look in the intake for anything ary. I'm not familiar with the v6 intake but I'd remove the throttle body and look in there - I assume you didn't or can't put the maf on backwards?
