OKAY, I will give it a test tomorrow to see the fluctuation.

 

I have given it a test during weekend.
Both reading are 0.65V, quite constant, ~ 0.63V - 0.66V during idle.

 

I'm going to try to show a screenshot of my sensor readings from my RX later tonight and I'll note my own. My own sensors have been there a long, long time, but they're not perfect, but the numbers you mention are similar to the ones I have.

 

Hi Lexmex,

Is my MAF reading good also?

I know I run within that range, but I am going to have to take a look at fluctuation. It's not the most critical thing (the A/F sensor readings are more important), but I'm going to show you my screen shot tonight and also note the ranges I'm seeing at idle.

I'm going to try to see what I note on the road, but I've got to set my software up to read the max/min first.

 

Okay, that's fine.
Thank you very much.

 

I'm going to have to wait until later today to do upload the screenshot. Our Internet is down and I'm on my phone typing this as we speak. We had a ton of rain and lightning last night.

 

Okay,

I made two videos of my computer screen that could better show the variation in idle.

Hi Lexmex,

Seems like your readings are the same as mine.
I will capture a video to show you later.

Here comes my videos.

I need to test something in mine perhaps this weekend when I throw the fuel additive in there (which I haven't done in a while) and then take a look at my numbers again.

BTW, I have on my 'drawing board' an intake design for ramming through cold air from the bumper. It's similar to designs I've done in the past, but this one shouldn't be ramming air in so that it messes up the IACV, but still prevents the hot air from coming in as much as possible. I need to get the right tubing for that, as I also curious to measure the A/F readings on that. I'm not sure when I will get to it, as first I'd like to get some new A/F sensors prior to starting that project.

Cold air is definitely a necessity here in Miami, whether for a/c or combustion.

 

Hello Lexmex, any good news?

 

I've got my new a/f sensors sitting on the dining room table, and I hope to be able to get to it today and take a look at the readings. Still need to go to the auto parts store to get some PB Blaster and a socket (I'll add some photos to the fine DIY we already have on the subject as I want to see how the stress of Mexico wore on these sensors...I have a few pictures of them from a few years ago when I did exhaust modifications).
