Ford F-150 - 1997-2003 :: Idle Down To The Point Where It Almost Stalls When Stop Or Park
Mar 11, 2017
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 am having trouble with my 1998 F-150...XLT Triton? I bought the wrong motor for it and installed it, turn out it's a 1999 Windsor 5.4
Problem is that it runs rough and stalls when I stop or rolling to a stop it would die.... It seems ok while cold, but when driven for 20 minutes or more it does it.
I have used original 4.6 harness as well as original spark plug coils and only replaced throttle body, oil filter holder thingy mount, exhaust manifolds are from 4.6.
When the throtle body was on the 4.6 I didn't have when the motor ran. Only misfire due to intake manifold leaking into the 3rd cylinder spark plug.(I thought it was a bad head gasket and changed in....installed the timing chain wrong and messed up the whole motor)
Also I broke a rear brake line and now it only has front brakes and smells like fried transmission oil.. This is my first truck and first truck accidental engine swap. Also the 5.4 Intake manifold is missing 2 coolant sensors and it's giving me the P0118 ECT Sensor Circuit High input...

I had what I was told was the breather (on the drivers side valve cover) snap off. I was able to place a piece of tubing In it and reconnect it. I had to change the #7 cylinder spark plug wire. Got a misfire code and found the wire was loose and corroded. Replaced wire and PVC valve.
My problem is, it seems not to be idling as fast as it was before this happened. The truck stalls out now in gear but not in park. 1997 F150 4.6 ....

I have a 2001 Ford Escape, and when I start it for the first time of the day, it idles really rough, and way below 500RPMs (to the point where it almost stalls). After about 10 minutes, when the car is all warmed up, it runs smoothly, as if there was nothing wrong with it. The only conclusion I can draw is that it is temperature related, but I can't figure out exactly what is causing the issue. This happens on the driest or wettest of days, so moisture doesn't seem to be an issue.

My buds 2003 4.6 liter stalls every time he takes his foot off the pedal. Runs fine otherwise, no roughness or anything, you just have to keep your foot on the thing to keep it from dying out.
We checked for codes and found none. I checked vacuum connections and they looked OK.
Is there an easy way to test the IAC or should we just throw a new one in and cross our fingers? If we do change it out, does the truck need to be driven around a bit for the computer to re-learn anything?

My dad has passed his 99 f 150 with 130,000 miles to me. It is a 2 wheel drive, extended cab automatic equipped with the 4.6. Recently, the blend door failed and as a temporary measure I installed a ball valve in the heater core supply hose. The ac now blows ice cold.
On two occasions since the installation of the ball valve, the truck has stalled at idle when in park and would not start, although it turned over fine, until 30 to 45 minutes elapsed. On both occasions it was a hot day. The check engine light is not on and no codes are stored.

I have a 97 ford f150 with a 5.4 I bought the truck with 114000 miles on it and the exhaust manifold bolts were broke from the exhaust I have replace the whole manifold with new gaskets and bolts and I get the codes 1131 and 1151 which indicates o2 sensors indicate lean and I also get p0136 and p0153 which indicate lean or front o2 sensors it will stay running for a little bit every once in a while but it only idles at 200 to 400 rpms and I'm not sure what to do?

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.

I have a 98 F150, 4.2 V-6, 183,000 miles.. Lately, she's been loping at idle. Especially while in gear... almost stalls. Once revved up, everything seems normal. Still goes up hills fine if I get on the gas. The light was on, and I got codes for lean condition on both banks.. (P0174, P0175).
I already cleaned all the sensors in front of the intake.
The MAF was real dirty, and the IAC was full of soot too.
They both cleaned up nicely, but it didn't work.
I borrowed a fuel pressure gauge yesterday, and it showed 12 psi with the "key on, engine off".
It showed 29-30 @ idle, and only went up to 35 when I revved it a little.
The guy at the store said the range is supposed to be "30-45 psi with the ignition on", but I'm not sure if that means engine running or not..?
Either way, it looks like the pressure is on the low side, so I'm going to change the fuel filter next (and hope for the best).
If the fuel filter doesn't fix it, what should I go after next? And, is there a way to test the fuel pressure regulator before buying a new one?

I have a '98 F150 4.2l with 230k miles on it. A couple of days ago when starting, I noticed that the engine kept racing instead of idling down like it normally does and the weather here in Arkansas has approached the 80 degree mark. The engine also doesn't idle down when shifting (I have a manual tranny). Where to start? I don't have any codes stored other than two for bank 1 and bank 2 running lean but they popped up many miles ago. I'm thinking either a vacuum leak or throttle control. I checked the operation of the cable and the throttle valve and they appear to be fine. Maybe the idle air control?

I have an 01 f150 4.6 4x4 automatic with 90,000 miles. I have an erratic idle but it only happens when I am on the freeway well actually when I get off the freeway and stop. the idle will fluctuate between 750and then drop to 400 then back and forth til I get moving again. I replaced the IACV because it was doing the weird humming and vibrating the intake tube. The humming is gone but still idles funny as stated above.

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 have a 1999 f-150 4x4 4.6 5spd manual 180,000 miles on the clock. My question is, when coming to a stop i push the clutch in an the idle hangs at about twice what it should be until i come to a complete stop then it drops to normal. It's not like somethings sticking cause it will stay at the high idle as long as were rolling but as soon as the wheels stop turning it drops down.

I have a 2002 F150 Supercrew 4.6L 2wd truck. Just added a set of 32" tires to it. Trucks runs and drives great, so thing I don't like is that around town in traffic it shifts into OD to so. Is there a way of changing the OD shift point?

I have a 2004 FX4 5.4 with about 113,000 miles on it. Lately, when towing the camper (around 7000 lbs), truck runs great. However, when I come to a stop, it idles horribly and even stalls sometimes. When I rev it up, runs fine again. It only does this after towing when engine is under load for extended periods of time.
The only code it has ever thrown was for bank 2 camshaft over retarded. My thought was that it could be VCT solenoid for bank 2...

My launch scanner reported a bad oil pressure switch, but I've replaced that, and when I did the oil pressure light went away, but my gauge still didn't work. Could it be a faulty switch? Or is it common for gauges to stop working on these fords seeing how there's a resistor to trick the gauge from the factory anyway? If I smack my dash the gauge will raise and lower. But I think that's normal.

Ford F-150, 1999, 4WD. My dipstick tube has rusted off right at the point where it attaches to the engine block. I purchased a new one but I'm not sure if that's a job I can do on my own. What installing a new tube will entail?

Stays open all the time. I'm guessing there is a spring somewhere that closes it. Is there a parts breakdown I can look at? I've looked around some but haven't found anything that looks related to this. 1997 F150....

I have a 1997 Dodge Dakota V8 (automatic) with about 140k and live in Vermont. Recently, my truck will konk out while I am sitting at a red light. As I'm sitting there, the RPM's keep going down below 700, until finally stalling out completely. When I shift into Park/Neutral then turn ignition, it will start right back up again. To get around this, I have been shifting into Neutral while I wait at the light, then back into Drive when it turns green. I have recently installed a new battery and exhaust system. I am wondering if this is occurring because of worn plugs, a dirty air filter, cracked vacuum hose, or bad alternator?
