Ford F-150 - 1997-2003 :: 2000 - 4 Wheel Drive Isn't Engaging Properly?
I have a 2000 F-150 4x4 and the four wheel drive isn't working properly. It does work,but to get it to engage I had to drive in reverse for a couple feet then it locked it and everything was fine,pretty sure that isn't normal. What could be wrong with it? As soon as I turn the lights up on the dash,but the front tires don't spin.

My 2002 F150 (50,000 miles) 4.2 is surging when cold. I just got done replacing the pcv valve. I noticed it was running better so I cleared the service engine light, but now is surging when the engine is cold. I live in FL so it does not get that cold like up north. The following codes were the ones that the pcu put out, P1131, P1115, P0174 and P0171. I am leaning towards changing the IAC valve and maybe the oxygen sensors.

Have a 2001 F150 FX4x4 and since the weather changed and started having days below 40 the truck has started running rough for about the first 15-20 miles. When you first start it starts like normal for first 3-5 min and then it starts loping real bad like it has a cam in it!
View 5 RepliesFord F-150 - 1997-2003 :: 2002 V8 - Rough Idle Only When Cold - O2 Sensor?
So I recently acquired a 2002 F-150 4x4 super crew with the 5.4 V-8. It idles rough (surging from 400 - 700 rpm) when cold, and sometimes dies, but more often then not it stays running. It runs and drives fine when the accelerator is pressed and when going down the road. When it gets up to operating temperature, and has been there for a while, it seems to idle fine 95% of the time. The codes I have are P0136 (bad circuit to O2 sensor), P1151 (HO2S detects lean mixture or something like that), and the infamous P0171 and P0174, which is lean exhaust/mixture on both banks. Now I have read extensively on the internet about these symptoms and have done the following:
Sprayed every vacuum hose with carb cleaner, and even around the intake manifold and injectors.
Considered the IAC (its new, the guy I bought it from replaced it a couple months ago) Torque app for android phone says vacuum is good. Cleaned the MAF and air temp. sensor with electrical cleaner Checked all of the vacuum hoses on the engine by pulling them off
Put grease around the fitting where the PVC valve attaches to the valve cover. Seemed to make it idle a lot better after messing with it, but I don't know if it was a result of the engine being fully warmed up, or my messing with the PVC.
What to try next? I'm close to just dissecting the top part of this engine and seeing what the intake manifold gasket looks like..or could it really be an 02 sensor?
Ford Ranger / B-Series :: 2003 3.0 V6 - High Idle In The Mornings When Cold About 2000 RPM
Truck is a 2003 Ranger EDGE 2wd auto w/140K miles (looks new) that was a one owner truck I recently bought. Came from Texas and is clean and was well maintained I got all service records up until I bought it in the fall last year. OK now the problems...
First...it has a high idle in the mornings when cold about 2000RPM. After it warms up it settles to about 800-900RPM but is VERY ROUGH to the point where it feels it will stall. I DID replace the spark plugs and the plug wires look newer and are not OEM. I DID remove and clean the IAC and it does not look very dirty but I did slightly clean it anyway.
When I did this I disconnected the battery for 20min. After I put it back together it ran smooth for about the first 10 minutes then same rough idle came back. I was told this truck has no EGR so that's not an issue. There are NO CODES and when I ran my pocket scanner nothing comes up either. Should I just go to NAPA and get a new IAC anyway? What else can I do?
Ford F-150 - 1997-2003 :: 2000 - High Idle With Codes
I will try to keep this short. Picked up a 2000 f-150 4.2 for my nephews first truck last night. Bought it blind against my better judgement, but the price was right. Got it home, odometer didn't work, fixed the solder joint and was happy it only had 132k on it. Heater core was plugged solid. Got it flushed and at least now its has luke warm heat until I have time for a full coolant flush and new core.
Next on my list is the high idle and engine lights. Its idles around 1300-1700, cold or hot sometimes it drops down. I only have a cheap scanner, but I have 2 codes. PO171 and PO174. Where should I start with diagnosing this? I would assume vacuum leak. Any common spots to check on these?
Ford F-150 - 1997-2003 :: 2000 - Rough Idle When Outside Temp Below 50
2000 Ford F150 1/2 ton 2x 5.4L... Last year, I started having a problem where when the temp dropped below 50 degrees outside, my F150 would idle really rough and sometimes stall out. The CEL came on and reported some codes that I don't remember but pointed to bad air/fuel mix. I consulted a friend and he suggested changing out the IAC. I did that just towards the end of the cold weather spell we were having and the engine ran great so I assumed it was fixed.
Well, the temps have been below 50 for 8 days now and ever since the temps dropped the problem has come back. I took it to AutoZone to have the codes read and they gave me the following:
P1151 - Lack of O2 switches -bank 2 sensor 1 : ECM could not adjust fuel trim because of a lean or rich condition
AND
P0171 - Fuel trim bank one condition : The powertrain control module uses the oxygen sensor to calculate the Air/Fuel ratio of the engine. The computer recognized a rich or lean condition on one engine bank only.
Both printouts that they gave me mentioned the following:
Poor fuel pressure
Bad or Malfunctioning MAF sensor - Dirty/defective
Oxygen sensor defective
Fuel injector problem - Leaking or fuel pressure high/low
Vacuum leak on engine
I again called my mechanic friend and he suggested cleaning the MAF and if that didn't work replacing the MAF. I cleaned it and the problem was better but still not fixed.

View 9 RepliesFord F-150 - 1997-2003 :: 2000 V8 Running Rough At Idle And Check Engine Light On
I started out with my 2000 F150 with a 5.4 V8 running rough at idle. It would idle way down slow and then rev up a little over and over. On a couple of occasions it would even die when in drive or reverse. I did finally get a Check Engine light so i put it on my diagnostic program to see what was up. Here is what I got:
P1151 Lack of HO2S21 Indicates Lean
P0171 System Too Lean Bank 1
p0174 System Too Lean Bank 2
After doing some reading up I checked all my vacuum hoses and cleaned my mass air flow sensor. I then got the same codes again after a few minutes of running. So I went to the next thing that was recommended, the upstream bank 2 O2 sensor. After changing it the truck ran fine for a couple of days, no issues. Then all of the sudden it idled a little funny again and I got a Check Engine Light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0300 Random/Multiple Misfire
I reset the light to see if I would get the same again later. Before the light came on again I filled my truck up with gas and it seemed to be running pretty good again. Then a day or so later it set the light again. This time:
P0171 Bank 1 Lean
P0174 Bank 2 Lean
P0136 O2 Circuit Malfunction Bank 1 Sensor 2
P0156 O2 Circuit Malfunction Bank 2 Sensor 2
P1131 Lack of Switches HO2S11 Lean
P1151 Lack of Switches HO2S21 Lean
I went ahead and drove for a few days as it had gotten really cold here and I didn't feel like messing around in my shop since it isn't heated. A couple days ago I needed gas so i filled up again. Suddenly the problem was gone again. Truck ran fine idled fine no missing or odd idling at all. That lasted a day or two before it started acting a little weird again. At that point i was down about 1/8 of a tank from full. I have read that there can be issues with the fuel pump.. I am kind of wondering if that may be it now. But I haven't had to deal with this sort of issue before so I am unsure what to check next. The truck always runs fine off idle, it only seems to have the issue when it is idling. I had reset the codes the last time and i have the light on again now. I haven't checked it yet but I am sure it is going be some combination of what i have had in the past.
I have read that the IAC valve can be an issue as well. I had a problem with mine sticking a couple years ago and when it would do it you could just tap it with a wrench and it would idle up. But it never died like it does now and it would also idle a lot slower than it does. Back then I cleaned the valve and had no more issues with it. The truck has always had times when it would act weird at idle usually after slowing down after being at highway speed. The current issue happens at all temps cold or hot.
Passat (B5) :: Cold Air Intake - Engine Does Not Idle Properly And Now Starting To Smoke
Today me and my son installed a new K&N air intake on his 98' passat 1.8t, everything looks good but when you start it up the engine does not idle properly and it now starting to smoke.. Also it is leaking some sort of black gunk out of the exhaust pipe, we didn't drive it but when you give it some gas it hardly accelerates.

I have an 03 Ford Ranger 4x4. Great truck and runs great just with one small problem. For whatever reason, every single time, the a/c only blows un-cool air (not hot) when I start the truck. Then, and only then, after about 30-40 mins of constant driving around does the a/c start working properly and blowing COLD air. After that it works great but it always takes about 30 mins after I start the truck for it to work correctly.

View 7 RepliesFord - Explorer :: 2000 - When Cold Won't Idle / Tries To Die?
2000 Explorer with the 4.0 SOHC.
It starts fine under all conditions but when cold, like in the 30s or lower, it doesn't want to remain idling, yet no CEL comes on. New fuel pump. The throttle body is cleaned, as are the injectors. It runs super once it gets past the cold startup issue.
I was thinking a sensor is getting weak but not weak enough to set the CEL.
Ford - Explorer :: 2000 Won't Idle When Cold / Hard To Start And Keep The Engine Running
I have a 2000 Explorer W/4.0 SOHC engine. With summer nearly over and fall on the way, I need to figure out what is going on with my engine. This problem has been going on for the past 2 years. As the outdoor temperatures get cooler, the harder it is to start and keep the engine running. This starts happening around 65 ambient temperature, and gets worse as the temps drop. By 30, I can barely keep the engine running.
Odd thing is, all I have to do if the engine starts is, keep my foot on the pedal to keep the engine around 2000RPM, put it in gear and start driving. After about a mile or two, the engine runs normally, and will do so the rest of the day. So far I have cleaned the air flow sensor, replaced the IAC, replaced all the injector "O" rings, and cussed a lot. I smoke tested the engine and the only vacuum leak is a very small one at the EGR valve.
Ford F-150 - 1997-2003 :: 2000 4.6L - Missing Only Between 1500 And 2000 RPM
I have a 2000 F150 with 4.6l triton 125k miles. i have a bad miss ONLY between 1500 and 2000 rpm. This will happen in any gear and in neutral, but only between those rpm's. seems to happen more constant in warm weather. This miss is so bad it feels like the transmission is going to fall out. but since it does it in neutral i doubt tranny problems. things I've replaced: fuel filter, tranny fluid and filter, crankshaft pos. camshaft pos, TPI, MAF, spark plugs, Ignition coils ( all 8) cleaned throttle body ( found 1 EGR port clogged completely )..
I had a couple codes but nothing constant. Been working on this for about 1 year. Codes p0320 (ignition speed input error) p0262 (injector circuit high cylinder #1). my only question here is...... What would only make this dang engine miss between 1500 and 2000 rpm. motor runs perfect thru all other ranges. idle... high speed.. and even throttling through this bad range is ok.. but when stabilizing between 1500 and 2000 starts jerking and missing like no fuel and no fire. i have put in superchip program couple years ago and it ran fine for about 1 year, then this trouble started... I have put back to stock program but still trouble.
Ford Super Duty (1999-2016) :: 2000 F250 - Choppy Idle During First 30 Or So Seconds After A Cold Start Up
My 2000 F-250 6.8L V10 has a choppy idle during the first 30 or so seconds after a cold start up in the morning then it smooths out and drives perfectly. If I were to place the truck in gear during the choppy idle, it would not die and throttle response would be fine.
I cleaned the MAF sensor and checked the PCV elbow for cracks (no cracks). It idles at about a 1000 rpm during a cold startup then drops to about 750 rpm according to the dash tachometer. The truck has 187,000 miles on it.
