2016 Toyota Tacoma- Rough Idle

https://www.youtube.com/watch?v=pd0d8It2P9k


Does anyone have the slightest idea what that clicking sound is? I've been having this problem for about two months. The dealership has replaced the ECU and a fuel pump, and they also found some slight corrosion some wires behind the right kicker panel. From the video it sounds like my throttle body is just going nuts. Does anyone have any idea what could be causing my truck to idle like this?

 

Two things I’d be looking for,...
1. Vacuum leak or pinched hose
2. Pull the MAF (mass air flow) sensor and spray it down good with MAF sensor cleaner. (no other cleaner)

 

Are those hoses sort of jumping when the sound happens? Take a broom or oar if it's metal and put the end all around the motor and the other part next to your ear. You will be able to pinpoint where it is loudest at least. I had a coil making a weird buzz sound that created a misfire. Ended up being a faulty spark plug but that broom trick located the sound so easy.

 

I think you’re spot on with the MAF sensor. After that video I killed the engine and have not been able to get it to restart until a little while ago I unplugged the sensor and the truck fired right up which doesn’t make much sense to me. Before then it seemed like the fuel pump wouldn’t engage at all then when the sensor is unplugged the fuel pump engages?

 

Sounds like the acoustical control inductive system or ACIS.

 

Having another listen, the clicking sounds electrical. Are there any blown codes?
This also happened right after the dealership did this work... Do you have warranty?
It’s possible you may have a coil spark jumping or a plug that’s crapped out. Toyota09 has a great idea on how to pin point where the noise is coming from. It may be a coincidence that issues happened right after the dealership worked on it but it wouldn’t surprise me in the least bit if they f$&k’d something up and didn’t tell you about it. It sadly happened far too many times like that for me but just check their work.
One powerful tool I have in my box is the ThinkDriver OBD2 module scanner. Even if you haven’t blown codes on the dash, it finds codes and tells you what’s wrong and where to locate the issues.
You mentioned wires were corroded. We’re they fixed, maybe unplugged or just left alone??
