What are your LTFt's are idle and cruise?Originally posted by alexgtp@May 13 2004, 11:00 AM
Car keeps throwing p-0171 code. LEAN SENSOR BANK 1
But my o2's are pegged at .95-1.00 at WOT!!!
WTF!!
From what I remember, the MAF and the 02 sensor was switched to try and find the problem.Originally posted by blitzu@May 13 2004, 03:20 PM
Probally already tried it but cleaning the MAF sensor wires with rubbing alcohol and a cue tip. Or just try replacing it. That code can also be set by a leak or ackward flow of air coming in. Did you remove your throttle screen lately? Adjust anything on your intake system?
I threw these codes on the GTO when I installed my intake system because of a leak, or possible oil from the k&N on the Maf wires.
Maybe this might help you.
I have some extra TB's if you want to try, but I don't think that's it. What I'm thinking is a loose connector at the vac port on the FPR/or related. It'd really help to just check it out, this kind of thing is impossible enough to figure out when you actually drive the car everyday. Those rich values have to be holding back your ET's. BTW, what are your IPW's like?Originally posted by alexgtp@May 13 2004, 03:27 PM
I just went out and disconnected the MAF. Problem still there HIGH Ltrims
O2's at wot over 1.00
I also disconnected the A/F guage// still the same problem. I tightened down the nut on the EGR tube to header.. Still the same problem..
Checked for Vacuum leaks.. none that I can hear or see.
Ron I have my original TB . You borrowed it and tapped out a hole for a possible NOS attachment. TB screen is still in. You never ported this TB to my knowledge.
If I was having a fuel pressure problem Wouldent I be running super lean at WOT and have low o2 readings? I dont have a pressure guage.
ALso I had the injectors flowbenched and cleaned at Justins. And that still did not solve the problem I am having.
Anyone HAve a TB for sale? LOL!!
ughhh Im going crazy..
It seems like his motor's getting a ton of unmetered air in from somewhere. Maybe the vacuum "T" under the snout? Does the car run bad? I'd expect his IPWs to be through the roof if his LTFs are 16. Maybe spray a little carb cleaner around the snout and see the rpms change.Originally posted by alexgtp@May 13 2004, 11:00 AM
