Fuel Trim and 02 Signals

1st gen Tacoma here with 2.4. Bought the Bluedriver off Amazon to help with diagnosing.

Had a misfire code on #2 cylinder. Checked out basic stuff but ended up just replacing the injectors. Solved the misfire but was having an issue with bogging on takeoff....no code. Replaced original maf...solved that.

No additional codes but looked like a lazy upstream 02 sensor based on data in Bluedriver. Replaced that. But actually have less power now...no codes still, which is good. Runs smooth. Since installing 02 sensor, I haven't put many miles on it, nor did I reset the ecu by disconnecting ground.

Here's a pic from inside the app for more info. Just wondering what some of you more knowledgeable folks think about this.

Thanks.

 

Nothing?

 

You short term fuel trim percentage shows you are rich as it is subtracting fuel.

 

Thanks for chiming in. Any thoughts as to why? Could it be that the rear 02 sensor is the weak link now or does it indicate something with the cat...

 

Leaky injector(s) or a hole in the pressure regulator diaphragm....how may miles?

 

New injectors and regulator. 364k.

 

Alright, sounds good. have you checked the fuel pressure? Are you burning oil? Still have cats?

 

What are the long trim numbers?
