Hey Skinfaxi, thanks for your input. I guess I wasn't completely wrong. So am I understanding you correctly? If the LTFT is consistently high this is normal? So when the info world says the normal range is +/- 10 is normal anything high is suspect for a situation. I understand it could go above...

:redbrick: That is so weird. Ok help me clarify. You have the 3400 correct? And I assume you have 4 O2s? Ok, I just like typed 4 lines and erased it. I'm just gonna continue reading into this Banks 1&2 stuff and its relation to the 2 precat O2s. We mite just have to agree to disagree...

You hit the nail on the head there. Confusing for sure. Yea that's weird that it didn't throw a PO171 and PO174, that kind of unmetered air isn't bank specific. But would understand that on a 4cyl though right?

Sounds good! Thanks. I'm here to learn and appreciate your input. But please understand, I'm not on here challenging anyones knowledge, I am just confused cuz I've been studying all this recently, and the stuff you are telling me is not what I've come across in my research. I don't mean to...

I guess I would need an example cause a PO171 and a PO174 is code for lean banks 1 and 2. Maybe I don't understand how this tells you specific cylinder.

I'm pretty sure bank 1 and bank 2 relates directly to the motor. Bank 1 being the side that has the number 1 firing cylinder and then of course bank two is the side that has the 2nd. And you can have a normal LTFT reading on one bank and a lean or rich reading on bank 2. This then tells you your...

Oh I agree, if you have years of experience under the hood! You can most likely be affective doing it that way. But for the one who hasn't and the ones who don't want to through parts at it till you finally get it right, I believe understanding the OBD2 system is very affective. For example...

Ok, I'll look into installing a fuel pressure guage. Just a couple videos I found very intersting and enlightning on auto diagnostics. 1: ScannerDanner, an autotech teacher 2: Schrodingers Box, he's an engineer of some kind I've been educating myself from these videos, and in no way feel I...

HMMM, well, if you read my original post you would see I stated I have cleaned the MAF, and my O2 sensors are both new due to the fact the catalytic converter got stolen. And I'm pretty sure running rich or lean can very much be caused from a fuel delivery issue. Understanding LTFT is one of...

Thanks blubill. Wow, 300k, awesome. And that's pretty good fuel mileage. My 2.7 4x4 5sp with 150k doesn't get that. I've got a thread going about my LTFT's, I think that's my fuel mileage issue. Anyway, thanks!

Hey iowajosh, yea I'm sure it doesn't work that way, but like my silverado, the LTFT is at 24% at idle then in all driving ranges it's around 7-9%. My mileage went from 16.8-17.2 mpg to 13-14 mpg. So when I take 13 x 24% it equals 3.12, so add that to 13 and its 16. Same results on the 4R...

Hey, cool, thanks Ammomac. I see I spelt Missouri wrong! Ha,ha, I think you got it right.

Thank you Mytoy4. Nice lookin rig ya got.

Hey thanks JayRolla for all the input. I'm still real curious if some one else chimes in with their scan tool readings on stock especially. Cuz for sure exhaust, CAI, different MAFs, will play a part in how the ECM is reading things. But it's my understanding that the o2's are what sends the...

In my research I've not come across what the max is for toyota, as far as when it will throw a CEL that is. Its seems to be pretty common to throw a code at 20-24% from what I've noticed across all brand of vehicles. See my silverado has the opposite problem. It has high LTFT at idle and...
