Ford Fuel System :: 2003 F150 - Service Light Randomly Comes On / Code For Left Bank Running Lean
2003 f150 supercrew with 166,000 miles on it. Daily driver. Service light randomly comes on and when code reader was put to it shows "left bank running lean." Will clear it and will randomly come back on. Truck seems to be running fine. No issues engine. Bad sensor? Or bad injector? Maybe way to test?

So I just replace my Cat. Converter with all new sensors in them. I just replaced my spark plugs. (I'm knocking out these check engine light problems) and I think I'm getting close to the root as to why these other parts went bad. Why my o2 sensor would be stuck on "lean" ....

I have a 2001 Exrursion 5.4L V8. The code P1131 comes up and it says "Lack of upstream heated oxygen sensor switch - sensor indicates lean - bank #1". I hear it could be the sensor that is bad or there is a vacuum leak. It runs like a champ, no spitting, no sputtering, no missing, no ruff idle. What do I need to do to fix it or where do I need to start looking?

I keep getting a lean bank code. I have cleaned tb and replaced one of the rubber lines. It only comes on when I take a good ride with the truck. Not sure what else it could be. I'm thinking O2 sensor maybe.

Ford - Ranger :: 2000 V6 - CEL Code Saying Both Banks Running Lean
I have a 2000 Ranger, with a 4.0 V6, 4X4, with 175,000 miles and it still runs great except the check engine light is on and it is saying that both banks are lean. I put in new plugs, all 3 O2 sensors, cleaned the MAF and checked for vacuum leaks, all to no avail...

2005 Ford Taurus, 6cyl, 3.0L, OHV, 90K miles. CEL came on and code read was P2272 with info "O2 Bank2 sensor2 signal stuck lean". Should I assume that I need to replace one of the O2 sensors and if so, which one ?? Not sure, but I think this car has four O2 sensors ??
View 6 RepliesToyota - 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.
Tiguan :: CEL Code P2187 / Running Lean At Idle
Driving home yesterday and a check engine light came on while I was at a stoplight. When I got home I plugged my scanner in and came up with a P2187 code, running lean at idle. Cleared the code and went inside to start doing my google homework.
Looking around various threads I'm leaning towards the PCV valve being shot. Seems like they go quite a bit and it describes quite a few of my problems going on; CEL, lumpy idle, and a bit sluggish.
Currently at 50k miles on my 2011. I've been Revo stage one for about 7k if that makes a difference too.
GTI 337/20th Anniversary :: CEL On - Code Is Running Lean With A Base One
I was parking today and when i looked up my CEL was on. So I got the code pulled and it turns out I'm running lean with a base one. I think it was? the mechanic told me it was my o2 sensor but I'm not sure which one it may be whether it be before or after the cat?

I got an 04 Nissan Sentra and I got a (P1273 Nissan - Air Fuel Ratio Sensor 1 Lean Shift Monitoring Bank 1) code that popped up on it. Looking to see what the probable cause for this code to pop up? Is this a rare code that popped up on this car? There's no noticeable symptoms going on with the car.

I picked up a really cheap Hyundai Elantra 2005 that the kid that owned it really beat up on. Right now I am trying to sort out the issues so that it can become my daily driver for the next few years.
Second issue, The check engine light is on and it is popping up a P0171 generic engine running too lean code. The car looses power sometimes and I can smell gas in the car. I have a friend that is going to be loaning me his MAC code reader so that I can see if it is one of the O2 sensors and if so which one tomorrow.
Ford F-150 - 1997-2003 :: Vacuum Leak On PCV Hosing - P1131 Error Code
I'm getting the p1131 error on my 2000 xlt f150 5.4l. I know it's usually a vacuum leak on the pcv hosing, which I did have at the back and replaced as well as other softer joining sections(3 to be exact lol), but I'm still getting this error. Changed out my plugs and cops(as they needed it) and the back two plugs on both bank 1 and 2(plugs 4&8) were both white! Since this is an obvious indication of a lean burning cylinder can I make the assumption my most likely problem is dirty fuel injectors on those cylinders?

View 14 RepliesFord Ranger / B-Series :: 1998 - Random Misfire / Power Loss / Hesitation - Code P1131
Ok I've been plagued with this very random misfire/power loss/hesitation problem going on a couple of months. You could drive the truck anywhere from 50-300 miles without having an encounter of this problem. It seems to do it now mostly on contiguous long trips over like 30 miles. It one time threw up a P1131 code which quickly went away on it's own. This is a list of stuff that has been recently changed: plugs, wires, coil packs, air filter, pcv valve, fuel injectors, tps, idle air valve, MAF cleaned, fuel filter, and egr valve.
I sprayed with brake cleaner for vacuum leaks around the intake tonight after driving a continuous 50 mile round trip it messed a few times on the way back. When I sprayed the EGR valve mounting area it idled rough when it was hit with brake clean and idled up. So there's a leak there. Or is it stuck? It will be driving normal and usually when you come to a stop the engine will start missing really bad and then when you take off there's no power at all. You keep your foot on the gas and eventually it will feel like all the power is just turned on.
If it does it while you're driving highway speeds it will feel like you've lost a cylinder but it's not as dramatic as when you come to a stop and it starts missing. I can't be 100% but I don't think the EGR wasn't leaking before I replaced it and it was still doing the same thing. I'm wondering why the Check Engine Light won't pick up an obvious misfire when you can you actually feel it. And why if it was the vacuum leak would it only start doing it after many miles of driving?
Ford Ranger / B-Series :: 1998 Truck Couldn't Get Any Speed In Gear / Code P1131 And P1151
I have a 98 ford ranger with a 3.0 v6 it has 228,000miles standard tranny but I keep the truck running great. I did the plugs and wires about two weeks ago and it was running fine, actually great. This morning I got into the truck to start it this morning and it barely started. It fired up but barely stayed idling. I would get into the petal and it wouldn't raise rpms. I had to get to school so I headed out. I couldn't get any speed in gear the truck wouldn't gain speed. It would sputter and pop and then all of a sudden it would go ok but then start popping again. I took it to a buddy shop and his scanner showed p1131 and p1151 both codes. I don't know what to do?
View 13 RepliesEscort :: 1997 - Getting Error Code P1131?
My car has lost power. The engine seems bogged down and it has a significant sputter when accelerating and acts like it wants to die when idle. I am getting error code P1131. AutoZone did not give me any info on the code. I have changed the plugs and wires. I have been told this might be o2 sensors but after reading other stuff here, it looks like maybe a vacuum leak? I am not sure where to start at diagnosing this issue.
View 14 RepliesPassat (B5) :: 2000 V6 Idles Very Low And Dies - Code P1131
I've got a 2000 passat v6 and lately it started running pretty poorly. Now it takes a good 15-20 minutes just to get it started and idles very low and dies until after awhile it will run fine. I plugged in an obdII scanner and got the codes p1131, p1423, and p1411. I am pretty sure the last 2 codes are just emissions codes I've had ever since i bought the car. I haven't been able to find a solid answer on what this code is. I imagine it has to be something along the lines of a mass airflow sensor or o2 sensor. I'd rather not go throwing all that money at my car if I don't have to yet.

I changed both started the rig up and heard loud rattling like metal maybe chain.

She had metal/plastic in her oil. I had all plugs done and actually i re did the 8th cylinder plug because it was miss firing and i pulled it by hand with only the socket no ratchet. I'm thinking the chain is going bad if not already bad. Only 113k miles my 04 f150 5.43v lasted 250k before motor swap...
