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?

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 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..
Ford F-150 - 1997-2003 :: P0133 And P1131 Codes After Changing Exhaust Manifold
Truck Specs: 1997 F250 LD 184000 miles and a 5.4, automatic, shift on the fly 4x4 extended cab.
What I did: Changed the exhaust manifold gasket on the right side. There were some broken studs which came out with a stud remover.. No torch was used during this evolution.
What happened: After driving 10-15 miles it set the codes that I listed in the subject line. Reset the codes 20 or so miles later the P1131 code set again. (both times there was a noticeable loss of engine power) The upper O2 sensor checked out with a meter. When I checked the voltage on the truck's harness plug referenced to the NEG terminal on the battery, both the power and gnd had 12V- Key On Engine Not Running (KOENR).
What I did: Cleaned the connections put dielectric grease in the connections and reassembled. Reset codes; all was well ~ 100 Miles later the codes are back. I also ran a continuity check from the plug to the control module, they check out fine.
Avalon 2005-12 :: CEL Error Code P0440 Error Code / Charcoal Canister Replacement
So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.
Ford 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 RepliesFord Excursion :: 2001 V8 - Code P1131 / Lack Of Upstream Heated Oxygen Sensor Switch
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?
View 3 RepliesCivic - Honda :: 1997 - CEL Came On With Error Code PO135?
I have a 97 Honda Civic Manual transmission and my Check Engine Light Came On. The error code is P0135 which shows up as needing a O2 sensor. My question is:
1. Do I need to replace it?
2. How long do I have to replace it?
3. Will driving with it as it hurt my car?
The weather is getting colder and I read that could be the cause. I really don't have much extra money but I don't want to kill the car. I have kept up on Oil Changes with MaxLife Full Synthetic, Radiator Flush, etc if that matters. I also went into Valoviline Instant Oil Change and they double checked all of the fluid levels and that was OK.

View 5 RepliesFord F-150 - 1997-2003 :: IAC Over Speed Error Code P1506
About 3 days ago I noticed my engine RPM was around 250 higher than usual. Usually my truck idles around 550-600 rpm (I know this is low). Anyway, yesterday it threw the P1506 "IAC over Speed Error" Code. It is idling very rough, shifting weird, but does crank up fine.
My truck is now at 93,000 miles and I just cleaned the IAC at 87,000 miles due to the common no start condition. I guess I am going to get a new IAC now since another code came up.
Well, my question is it came up with two other codes also:
P0171 - System too Lean, Bank No. 1
P0174 - System too Lean, Bank No. 2
Do you think the P1506 (IAC Code) made the O2 Sensor codes show up or is it really the O2 Sensors? I just changed my two upstream O2 Sensors around 90,000 miles. Should I get a new IAC or try to clean it again?
Ford F-150 - 1997-2003 :: 2002 - Got Error Code PO174
Looking for some experience/recommendations for the "what to do" and "in what order" for an error code. Recently the "SERVICE ENGINE SOON" light came on and has stayed on for the last 2 weeks. It has don this before after a heavy rain but went off after a few days but not this time. I took it to Advance Auto who hooked it up to a Trouble Code Reader and got back "PO174- Bank 2 system to lean". From what I've read from the Haynes book and other forum postings this is either a O2 sensor issue or a intake manifold gasket issue? Does this sound right? Next is how to go about addressing this issue in a systematic manner so as not "fix" 10 things that don't need fixing and not running to mechanic and paying a buttload for something I can do myself for less.
View 1 RepliesFord F-150 - 1997-2003 :: Multiple Exhaust Manifold Studs Broken On Both Side / Codes P1131 And P1151
I have a 2000 with a 5.4 and 166K miles. It had multiple exhaust manifold studs broken on both sides. Now that thay is fixed, I am getting the p1131 and p1151 codes. The EGR tube was also replaced at the time of the manifold fix. I checked over all the tubes and electrical connectors to rule out something simple but did not find anything out of place. The intake manifold was replaced with a new Napa one less than 5K miles ago as well.
Could the leaky exhaust manifolds over time set the fuel trim level high and now that they are fixed, the ECM is thinking it is running too rich? Can the ECM be reset to zero? There is also a ticking/rattling noise when you accelerate that seems to be coming from the fuel injectors. I listened with the stethescope and they are the only things that sound like the noise I hear. Could these all be related?
Ford/Mustang :: 1997 - Getting Error Code P0304 / Cylinder 4 Misfire
1997 Ford Mustang 4.6L EFI engine with 67K miles. The engine is actually now in a Factory Five Roadster. It sat on a stand for 5 years but runs well now with the exception of the code. I keep getting a code P0304 (cylinder 4 misfire) and I've checked the plug - the code seems accurate; it is misfiring.
Things I've tried:
1)swapped plugs,
2)this is a dual coil engine so I've swapped coils,
3)the #4 plug is the longest sparkplug wire so I've gotten high-performance wires,
4)heavily grounded the AL head,
5)put dielectric grease on the plug,
Still, ONLY cylinder 4 gives the misfire.
Ford F-150 - 1997-2003 :: Got Error Code P1000 - Idle Rough - CEL On?
What that means? The check engine light is NOT on but I looked for a code because my truck is idling rough, and when driving, when the overdrive kicks in, it vibrates really bad. As if a bad U-joint on your drive shaft. The truck has been in a field for about 5 months broke down so any clue? Haynes manual says nothing about P1000.
View 13 RepliesFord F-150 - 1997-2003 :: 1999 - IAC Over Speed Error Code P1506
1999 F150 4.2L 125K miles.... My problems started about a month ago. I had a P1506 error. The engine was running fine but received the error code. I replaced the IAC and the air filter. Engine still running fine. A week later I received a code for the Intake Air Temp Sensor (don't remember the code). The engine still running great. I bought a new Air Temp Sensor and noticed the wires from the Air Temp Sensor were rubbing against the belt and had been severed. I made a mistake when replacing the air filter of not checking the wires (confession is good right).
The engine also constantly ran a fast idle 2000 to 2500 at this time. I repaired the wires. The engine light went off and idle now starts great and smooth but when heats up will will go to 2000-2500. I then decided to replace the Air Temp Sensor hoping to fix idle problem. Engine still idle fast when warm. However, when I come to a stop and put in neutral the engine will take a minute but go down to normal idle after sitting. Engine light stayed off for a week. Now engine light back on with original code P1506. Idle is still not working correctly.
I feel like I made it worse than it was originally and not sure what to try next.
Ford F-150 - 1997-2003 :: Check Engine Light Came On - Error Code P0420
I was driving along today and my Check Engine light came on. I stopped at the nearest Advance Auto to have them pull the code and it came up with the P0420, Catalyst Efficiency Below Threshold (Bank 1). I asked what could cause this and they mentioned that the fuel that was put in could be causing it. They didn't mention any other possible causes. Any others? I'm thinking it could be the fuel because the last gas station that I stopped at and filled up at is one that I never go to, and maybe just got a bad batch of fuel.
