Ford F-150 - 1997-2003 :: Bank 1 Too Lean Code

Well I got the ubiquitous "Bank 1 Too Lean" code this morning. Yesterday I changed out the PVC Valve, Elbow and Hose assy.

I changed out the hose from the intake to the canister purge valve on the firewall next to the master brake cylinder, that one was like dust.

Today I'm changing out the rear O2 sensors, but I may change out the fronts when they get them in (very rural area hear).

I'll keep looking for vacuum leaks and change out the MAF sensor. I hate to think it may be the intake....

Ford F-150 - 1997-2003 :: Vacuum Leak / Bank 1 Is Slightly Higher Than Bank 2

I am in the process of trying to chase down a vacuum leak on my 2003 F150 with the 5.4. I have checked all lines and cannot find it. I decided to check the long term fuel trim and noticed that my bank 1 is slightly higher than bank 2 (screenshot attached). Is this enough to assume the leak is on the bank 1 side?

Corolla / Matrix 2009-13 :: 2010 Does Code P0037 Is For Bank 1 Sensor 2 Oxygen Sensor?

I have a 2010 Toyota Corolla 1.8L, the base model.

I recently had a check engine light, VSC off light (blinking) and traction control light come on. I took it to Autozone and had a p0037 code ring up for a new Bank 1 Sensor 2 oxygen sensor (downstream). I believe I have found the correct sensor (located under car, approximately near drivers seat) and it looks simple to replace, aside from the fact that the wires go through the car body.

Can confirm that I have located the correct sensor? And if so, what is the best way to get to where the wires connect?

Is it located under the drivers seat? What should I do about the rubber grommet located under the car where the wires appear to pass through?

Ford - Mountaineer :: 1998 - P0153 Code On / Off Occasionally?

I have a 1998 Mercury Mountaineer AWD 5.0L V8. I've been getting the P0153 code off and on for about 3 months.

I read on another forum that bad gas caps can cause the problem, well, I've replaced the gas cap with a new OEM one and that seemed to stem the tide a bit.

As it often seems to pop back up when the tank is 1/4 or less, I fill the tank, and that works some. But it still happens.

This Thursday, 2 days after I changed the spark plug wires, it began misfiring on the #6 cylinder and the P0153 code came back and stayed on.

I swapped the #5 & #6 plugs, cleaned up the area and reinstalled the wires with dielectric grease. No more misfire, but the code did not clear.

So, I also changed the O2 sensor that kept kicking off the code. I used the OEM, Bosch O2 sensor.

I started it and it ran beautifully. Next day, I was driving and that damn code came back. I stopped and had breakfast, it was gone.

Off and on all the rest of the day, disappearing even while I was driving

Toyota - Camry :: Code P0171 - Lean Bank 1 Sensor 1

I have a P0171 code (lean bank 1 sensor 1) on my 2002 toyota camry 4 cylinder. I don't have any other codes except for an unrelated P1780 neutral safety switch code. It has had both codes for over a year.

I have replaced the fuel filter, the upstream o2 sensor, and the PCV valve. I also cleaned the MAF sensor. The mechanic performed a smoke test and found no vacuum leaks. Did a fuel pressure test and it's normal. Mechanic thought it would be fuel pressure because the car starts a bit slow when cold, but nope. The car runs great and still gets great gas mileage. I've never experienced a misfire in my 12 years of owning the car. I am asking because I am at a loss as to what it could be.

Ford F-150 - 1997-2003 :: 2000 - P0136 (Bank1 Sensor 2) Code

I recently replaced both the downstream O2 Sensors in my 2000 4.2L F150 because I was getting a P0136 (Bank1 Sensor 2) code that I couldn't get rid of by cleaning the connector or fixing wires. 110K miles. Calif truck. No other codes and has always passed smog test easily.

When I pulled the sensors, the Driver's side unit was extremely sooty, as compared to the passenger side (bank 1). The code failure was on bank 1.

Is this normal or is there some rich condition on the driver's side bank that I need to check into ? Originals were Bosch, replaced w/ Motorcraft, if that makes any diff. One on left is driver's side unit.
