That actually was bad i bought a new one hoping to solve the issue after a few test and when i installed it same issue 12v was back feeding to the switch trying to power all the relay contacts I’m guess or something. Just glad i finally figured it out had my scratching my had for a minute. I took a page i learned from you on using service manuals and certain electoral test. So as always thanks for all the help and knowledge.
Ok i feel stupid lol it was the relay that i figured to overlook. Ages ago when i first bought the truck i replaced it because i had no power to the switch so for the first winter i hooked 12v direct into the relay to the motor well after a burnt out motor in a month i replaced the blower and ran a switch straight from 12v to the blower for full speed well i hate being hot so i wanted a lower speed so i kept looking until i found the idiots cut before cut the ign feed brown wire so that solved that but no speed i think i fried some thing feeding 12v to the new relay a year ago so i hooked the old one back up and bam works great.
Cleaned the maf again and the fuel numbers stayed the same about checked the pbb same thing but i noticed it only starts to take fuel away when it’s above idle under and throttle movement and the maf reading goes up and down even under steady 2500-3000 so i’m wondering is that a sign of a screwed maf?

[quote=”wysetech” post=98042]Looks like a lean condition under moderate load. Try cleaning the mass airflow sensor and erase the fault code and recheck the fuel trims.[/quote] funny thing is when we replaced the bad o2 we cleaned the mass airflow sensor and throttle body ran fine for a week. After a week the code came back so now I’m starting to think it is bad.

[quote=”college man” post=97927]The p0171 means your running lean not that the o2 has a problem.
see if this helps.http://www.justanswer.com/toyota/6xczc-2002-toyota-camry-check-code-p0171-can-tell.html
I know that the Sensor it self in voltage and testing it off the car told me it was bad lol. Thanks for the links i’ll give em a read apperciate the help.

[quote=”ToyotaKarl” post=97943]Could very well be a vacuum leak. If the booster is leaking it can cause this. I would suggest disconnecting the vacuum line of the booster and plugging that line and see if the LTFT drops.

Thats what i thought i had a issue on a older car i used to have and did that but was skeptical it still worked on the new obd2 cars. Thanks for the advice and help i apperciate it.[quote=”ToyotaKarl” post=97943]Could very well be a vacuum leak. If the booster is leaking it can cause this.

well i ended up buying a used service manual and an going to try and find out if i can reset the pcm my self because im a a loss honda says the fuel trim is normal nothing with the engine ,cars lifted to normal i mean the only think i can think is that v6 hates me because i only maybe put 6 miles a day on it lolor honda’s lying hoping i’ll break some thing and there get to fix it which i dont believe . one question i do have is do the scan tools actually know if the o2 sensor are really working or is it a quick test it runs ?maybe a clogged cat car does stink if i lay on it hard for a while .some day maybe i need to swap it to a 5 spd turbo diesel engine there i’ll get the good mpg.
