Tiguan :: CEL Code P2187 / Running Lean At Idle
Jun 3, 2016
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.

I have a 2006 Hyundai Sonata with a 2.4 liter 4-cylinder engine. After filling the gas tank, the car idles roughly, but accelerates and performs fine at higher speeds. The rough idle lasts about 5-10 miles and then goes away.
Six days ago, I changed the spark plugs and air filter. Four days ago, I filled up with gas (and had the same issue with the rough idle). This morning, I started the car and idled it for 2 minutes while I scraped ice off the windows. I drove the car about 5 minutes and the check engine light came on. I took it to Autozone and the code given was P2187, System too lean at idle bank #1. "
Autozone suggested that it could be an air intake fault (MAF sensor), fuel pressure, or vacuum leak. They also said they have a MAF sensor cleaner to try. I am not sure if the rough idle after fill-up and check engine are related. Also, I don't know if the spark plugs or air filter could be related to the check engine. I was planning on making some easier checks first such as hoses near where I worked last weekend, especially near the air filter. Cleaning the MAF sensor is easy too. I was also going to check for vacuum leaks (incl. intake manifold) and recheck the spark plugs.

My wifes 2007 Santa Fe Limited 3.3 has had a check engine light going on a year now. Car has about 122k on it now. Scanned codes about 6 months ago and had a fuel system lean code. Did some reading and ended up replacing the purge valve. The CEL stayed off til the end of the drive cycle and came right back. I have noticed when you fill the car up there is a real strong smell of gas but the car always starts right up. It now has a P0171 Fuel system too lean (b1) and P2187 Fuel system too lean at idle. Where to start. Don't have much background with hyundai. Also the ESC off light comes on randomly and goes off. Doesn't happen real frequently though.

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 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...

I have a 1999 Ford f150 4.6L automatic. My check engine light had been on for awhile so I dug out my DTC code reader erased it, came back on 10-15 minutes later. I got the code P1131 sensor indicates lean which you would think is the O2 sensor a week later it won't start. Then randomly a couple days later it starts then that night it didn't. Hear is the parts that confused me. I don't believe an oxygen sensor would cause it not to start, it's cranking nice just won't turn over. And when you get the code P1131 I believe it bay 1 where the readings are off Well here's my readings.
Fuel system 1 CL-FaultCalc load 34.1%ECT 201.2 FSTFT B1 -1.6%LTFT B1 0.0 %STFT B2 -1.6%LEFT B2 0.0%ENG RPM 1101VEH SPEED 27 MPH
It looks like to me bay 1 and 2 are off? I'm not mechanically challenged, but not a mechanic either, I do most my own work on my vehicles..

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.

My truck out of nowhere will start to idle low and die when put in reverse or drive then on other days sometimes it will start and run right. I got the code 44 witch it could be a o2 sensor but tomorrow I'm getting my catalytic converter took off and run straight pipe do I still need a o2 sensor without a catalytic converter or what's causing lean exhaust?

I have recently purchased a 2011 F150 Ext cab with 3.5L ecoboost with 69k miles. I have no experience with these engines prior to now. I've always wanted a full size truck and after driving my 98 S10 for 17 years, I decided it was time for a new truck. I hope I made the right choice in going for the 3.5 instead of 5.0.
On to my question. I've noticed that the truck hesitates from a dead stop or anytime the RPM's are under 1k. It feels like its missing or running lean/rich during the spin up of RPM's. When I drive it hard, it does seem to subside for a little, and I've heard people say that they run better when run hard. I can attest to that, but is this hesitation normal for an almost 70k mile engine? I am getting 15ish MPG on almost all city driving since I have bought it, but I do expect that to change (job hunting and current commute is less than 2 miles each way).
The only time I get to open it up is when I go run errands out of the immediate local area or visiting friends and family. On one of those trips, before I noticed the hesitation, I attempted to accelerate from 60 to pass on the expressway and it bucked and resisted like a horse. It finally took off up to 80 and completed that journey with no issue but the check engine light came on for a bit. The check engine light went off when I shut it down and hasn't come back on since.

I've worked for months on this truck and I now have it in the shop. The truck shows a 41 code and has a lean miss at idle that get worse during acceleration and cruise. The injectors were refurbished 6 months ago and the ECM was replaced 3 months ago. All sensors are new and within specs. Fuel pressure is good and there are no vacuum leaks.
The mechanic has verified that the condition is not electrical related. The O2 sensor will react if carb cleaner is sprayed into the throttle but other wise shows constantly lean. He's now checking all pins at the computer for any off condition. He is suspicious of the refurbished injectors. I'm wondering if the computer somehow went out again. Which way to go or what/how next to test?

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?

My 04 F150 has started having a rough idle. While in park the engine will stall out with the A/C off. Also when in drive the truck will idle close to 1000rpm's. I had to the fuel filter cleaned and also the MAF sensor cleaned. Also did a vacuum check on it. Pulled the code and it's throwing a Lean Code. What else should I be looking for?

I am getting a CEL and the error code is p2187 engine too lean at idle. I have been reading around to try and find the issue, some seem to say PCV could be the issue. I have also read a test would be try and remove the oil cap while car is idling. I did this test and the oil cap was difficult to remove and the idle got really rough once removed.

I have an intermittent check engine light that's popping up due to a P2187 code. The CEL will come and go, and if I clear the code it it'll be back within the next week or so. The car is a stock 2011 GTI with DSG. What I need to be looking at to get this sorted out?

Went to the dealer because my idle was running both too low and/or too high, check engine light came on.
1) Replace air intake manifold because air flow flap is faulty.
2) Oil leak out of upper and lower timing belt covers - need to replace gaskets.
3) Missing!!! the high note horn

Got an intermittent CEL a while back and my indy took a look on Thursday. I don't have the codes, but he advised it was running a little lean and there was an issue with the high pressure fuel sensor. Replaced the sensor on 4/11, cleared the codes, ran the car for a few miles and no codes and no CEL. I put a couple hundred miles on the car with no problem, but on 4/16, the CEL returned. I'm dropping it off with my indy again tomorrow, but I'm assuming it's the lean condition again.
Plugs?
O2 sensor?
Injector?

My CEL turned on about 2 weeks ago. I took it to autozone and they ran it, and it came up as that my car is running too lean. Would this have to do with my MAF sensor? Also, It seems that my car is also burning oil. I have a 06 passat 2.0T.

How much boost can you push on the stock turbo without it running too rich or lean?

I own a 1996 Mazda Protégé with 128,000 miles. I had it in for a check of a sewing machine sound. The mechanic tested it and found, among things, a "lean running condition". What does that mean?
