Ford - Explorer :: 2003 - Idle Surge When Stop At A Light Or Just Running In Park - Code P2197
Oct 13, 2012
I have a 2003 ford Explorer xlt v8 4.6 with a P2197 code.(02 sensor bank2 sensor1)...
I had code P2195 a few months ago and replaced that 02 sensor but just recently truck threw code P2197 and is now starting to idle surge when I stop at a light or just leave it running in park.
Replaced PCV valve and the hose that goes from pcv valve to IAC also replaced Fuel Filter. Cleaned IAC, Throttle Body and MAF did the old check for vacuum leaks with can of carb cleaner nothing found.
Pulled all coil packs off checked OHMs all read .6,coil boots looked to be in good shape going to replace spark plugs and 02 sensor.

2001 f150 supercrew 5.4 triton... Recently did a tune up plugs,coil packs,filters,belt the whole 9 yards. The truck starts fine accelerates great and cruises down the road great without missing a beat.
But every now and then when you stop at a light or park it begins to idle down to the point where it almost stalls. When it does this i usually stab the throttle and it revs right up without missing a beat and idles fine for a a while then same thing all over again.
Could this be the idle air control? Seems like something simple due to the fact it runs down the road and accelerates like a big dog.

I have 2007 explorer with the 4.6 V8....
Recently it started running horrible. Rough idle, drives badly, hesitation, etc. Check engine light is on, code P0171. I cannot find a vacuum leak, and i am pretty much at a loss. Before it started running poorly i replaced the thermostat, and flushed the coolant. I am assuming this is a coincidence.

126000kms on 03 explorer 4.6 truck started. Running rough at idle and under load.... Code came up for cyl 8 injector. Replaced injector... problem still there. Switched cop and plug with another cyl and plug.... same code and cycl 8 is definitely not working. Would a generic problem always affect i cylinder. I even checked wire clip on for injector... it appears ok. There is power to injector wire clip.

I have a 1997 f250 2wd 8800lb with dual tanks with the 5.8l. Recently the truck will all of a sudden stop running, always at idle. I switch to the other tank and after 5 secs. of cranking it starts. Switch back to the front tank runs fine. Same thing happens the next day, 3 consecutive days now. Is this something I can fix at home or do I need to get the truck to a shop.

I got a strange one. 03 expl 4x4 xlt, started making a weird sound, almost like a rubbing, or a light grinding, comparable to the sound and seat of the pants feel you would get if say you ran out of good brake lining and were creeping the car forward at half mph while dragging the breaks slightly but (except it is when you are stopped and in P). Break pads are fine, just when you come to a stop and put it in park. lasts for about 1-3 seconds. No tranny slippage or other issues yet, all seems to be working. I don't use 4x4 hardly at all but not in last 6 months since there is no snow. Since it is so short I cannot pop the hood to track it down. Torque converter? Fan clutch?

2003 Limited with 4.6, 89K miles. Just started doing this last night. Checked codes, had the DPFE one pop up. Replaced that, no luck. Cleaned the IAC, MAF, throttle body, EGR, PCV, no luck. Used carb cleaner and sprayed around intake & vacuum hoses, no luck there. Checked vacuum, steady 20in even when it lopes. Battery unhooked for 15 minutes. It hovers around 300-400rpm's, sometimes will stall but drives fine. Tested the IAC and it is functioning normally. Nothing above has worked.

I recently purchased an 06 f150 fx4 5.4L with 60K miles. Just recently my check engine light came on and I've noticed a slight rough idle in park. I took it to autozone and the code read P0422 evap emission leak. Bought a new fuel cap but didn't work... EGR valve?

Just purchased a 99 passat v6 and it has a low idle surge and stalls when coming to a stop.It runs fine until it heats up about 15 min. then it surges up and down and stalls.

2003 ford explorer 4.6L. This truck will start and run rough high temp low oil light come on and temp gauge is pegged hot. Oil gauge is fine though, checked oil its fine.
I checked coolant reservoir its ok.
If I shut truck off and restart it will run ok and rev like normal and then all of a sudden go into limp mode and will misfire etc...
What sensor seems to be the main culprit?cht sensor???

I've got a 2003 Ford Explorer The transmission O/D light is flashing, and the check engine light came on. I'm getting and Code of P0775 Pres. Ctrl Solenoid B Circuit Malfunction. Also it shifts rough between gears, the rpms ramp up to much before it shifts. What the problem is, and how to fix it?

The revs surge from low idle to high (about 1000 rpm) every few seconds, but only when the truck is in gear,and the AC is on. What it could be. Also is it something I could fix myself? I have been driving with out the AC for a while but going into summer I need it on.

My 2003 6.0 has started to surge at idle after driving for awhile. Like when I drive to work (30 min) and pull off the interstate the idle will bounce around at the stop sign (only jumping like ~100rpm). Does this sound like the ICP to you? I've replaced it once before and am wondering if it's time to do it again?
Also the truck will sometime be hard to start. And when I say hard to start I mean turn the key, let the GP cycle the turn to start and it just cranks. But as soon as I turn the key back off and cycle the plugs again it'll fire right up. It doesn't seem to matter if it's hot or cold. It's been doing it since I got the truck. It seemed to get better after the 1st ICP but didn't completely get fixed.

2 questions regarding our 2001 F150 Supercrew. My 2 questions are:
My 2001 Ford F150 Supercrew (5.4L, 230,000 miles)has the check engine light on with the code reader telling me that it is the P0174. The truck would run rough when cold (usually in the mornings) and sometimes it would get close to stalling out when coming to a stop light. So we would quickly put it in park and give it some gas to rev it up a bit. After the truck gets warmed up, it runs great with no hint of the rough idle. Since this all started I have changed out the PCV valve and replaced the PCV hose (including the elbow). I have also replaced the Idle Air Control unit but that didn't really make a difference.
We then experienced a cylinder #4 misfire which we resolved by changing out the cop with a new Motorcraft unit. The misfire went away but we still had the problem of running rough at idle to the point of stalling out at stops when the engine is cold. A few weeks ago we cleaned the MAF sensor and that seemed to work. The truck doesn't run as rough now (when cold) at stop-lights, but occasionally it will still have the loping idle. We cleared the check engine code and it stayed off for about a week before returning.
I don't know what else to check other than trying to see if there is some type of vacuum leak, but I don't have access to a smoke machine nor would I know how or where to hook one up. Removing and cleaning the throttle body would work? What could be causing the trouble, or what I should do to further isolate or troubleshoot the problem? I saw a you-tube video on the F150 intake manifold gasket possibly being the problem and although I hope that isn't the trouble with my truck, if it is then I will have to deal with it. We need the truck to get to work and the car is now due for a registration renewal, but we can't get a California smog certificate with the 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.

My explorer has been running a little rough, particularly at idle. When I take off from a rough idle, it'll run rough until I hit 25-30mph. I ran by O'Reilly's hoping to pick up a pack of spark plugs and be done with it, ended up leaving with a new MAF sensor. It ran better for about 10 miles (I'm a delivery driver, so I did a lot of stop and go immediately), before it ran even worse than it did before, but at least my CEL finally came on. Took it back to O'Reilly's and they read a MAF sensor code and a catalytic system code (didn't ask for the codes, and now realize that was a mistake).
So today I took it to a muffler shop to have the catalytic system diagnosed. They looked at it for 10 minutes and told me they didn't think it was the converter. They said it seemed more like the EGR valve or solenoid, or the IAC. He scanned the codes again and got multiple "running lean" codes (0171, 0174, etc). The guy said I didn't have a vacuum leak, so I think I can rule that out. Unfortunately, the truck idled fine the whole time so he didn't feel comfortable giving me a definitive answer. He told to to leave the EGR valve hose unplugged for a few days and see if anything changes. I'm thinking about running a bottle of fuel cleaner through it or taking off the IAC and/or EGR and cleaning them myself.

Recently I have noticed that when on a tune other than stock I am getting a surge at idle - my RPMs drop to around 621-630 then shoot back up to 660-675. On my stock tune my RPMs stay around 640-667 and don't cause the surge (felt as a shimmy so to speak). Is there anything else that causes a similar symptom? I attribute it to tuning due to it only happening when running anything but stock but could be wrong.

1994 Ford Explorer; When I start it, if I don't step on the gas it will stop. If I give it some gas when I start it, the engine will race and then decelerates about 2000 rpms and keeps doing this, it does get better as the engine warms up. But the idle is really rough. It has new wires, plugs, vacume lines, oil change, air filter and battery. If I put the gas pedal to the rug, it will go from 4000rpm back down to 2000rpm and continue doing this as long as I keep the pedal to the metal. I had it put on an analyzer and it didn't read anything.

2009 Ford Explorer - 6cyl -4L - 36K miles. This morning driving it, I came to a stop sign and as I was braking, the idle starting going up (and up and up) to the point where I had to shut off the engine. When I restarted it, everything was fine and of course, I can't reproduce this. I have the shop manual and couldn't find an IAC valve on this vehicle which I'm assuming it doesn't have. I'm sure I didn't accidentally hit the gas (as opposed to the brake which I know I was pressing down on when it was happening). Years ago I had a different Ford which had the exact same symptom and replacing the IAC solve the problem.

2001 F150 5.4 Auto ... Truck was running excellent. Engine light and overdrive light begins to blink and it acts like its running out of fuel or water in gas. Baring made it home. Cleared the code and it comes back. Transmission seems fine.
